fucking pussies

lower iq, in case you breed with a nigger (you know sub saharaian iq is around 60)

Nothing

are you wearing a red clown wig on top of your hat?
you look retarded

it's called a hoodie retard

Oh look it's an American nigger poster. So this is who's behind every "whiter than you, muhammad" post.

Mental retardation, which leads to regression of the means, which leads to rootlessness. The cycle repeats.

An earring is gay.. but TWO earrings?

so why do you need to put a hood on your head if you are already wearing a hat wearing a hat?
something a retard would do

Look mums I amz's double cool

Fuck you you kaepernick squidward wannabe leftist soy boy!

punkass faggot with earrings!

You're being super rude user

oh and the only hope shit skins have to improve their genealogy is to mix it with superior white genes
prove me wrong.

I see nothing wrong with race mixing.

If you ever opened your mouth to me in public, I’d break your jaw like the spun-glass twink you are. Nigger. Shitskins. Spade. Coon. Slave.

you sound jellybeans

Shoo, monkey. Not even beaners like your kind.

You end up looking like that mongrel dumb son of a bitch, with race mixing, OP. Race-mixed nigger trash are literally worse than full blooded niggers because you have shit to prove. Nigger.

Because you are mixing the genetics of niggers who are behaviorally ill suited for our civilization with genetics from the group that created the civilization. The problem is less pronounced with spics and is relatively subtle with asians but it still exists.

Nice earrings fancy bitch.

killer bees. human hybridization and insect hybridization both produce individuals who are not accepted because they have unique features that make them too powerful. This is why extremely beautiful, powerful, strong, or charismatic individuals are found among the hybrids.

They have unhappy lives because they are not accepted; essentially their flaws do not fit snugly into the flaws of one race or another, making their lives very difficult.

If you want killer humans, by all means, have a child with someone who doesn't look like you. If you want a family, if you want your child to do something other than be unhappy about not being able to pass for an ordinary member of society, make a kid who isn't going to be called "mixed race".

...

>Hey guys I don't know anything about hoodies because I can't get any warm, fashionable clothing in my shitty 3rd world country.

>like those lies?

that's the stupidest shit I've ever heard, get on my level faggot bitch

You look like a tranny.

>warm, fashionable clothing
fag detected
who the fuck talks like this except a fag

Niggers by definition don't know that that they look or act retarded. The hood over the hat thing does help the cops know who's the dumbass before the witnesses point them out, so there's that.

You sound small, weak, and cultureless. The difference is that I am correct.

Half-breed niggers are the worst. They almost blend in, but have all the blackest nigger characteristics. Never trust a half-breed, as they have things to prove and generally hate their white heritage. Self-haters are the most dangerous.

holy shit

a light carmel with deep blue eyes might be better than the blondes

This spigger owes me 14 years of lunch money, this mystery meat looking faggot

Those are some ugly nigger bitches in the making. Race-mixed kids/adults just use their mongrelness as a weapon anyway. Theyr'e black and white at a whim.

the blue eyes dissapears when they grow up and turns brown

I just can't get over how undesirable the nigger in the picture is. That is literally the picture of rot in America.

>be faggot looking pretty boy mulatto with two faggot earnings, a clipped eyebrow, and a stupid red rag on his had while wearing a hat.

>be racemixed so intelligence is lower and not understand genetics and maths

> not realize that if nigger and white racemixing continues unabated that in six generations, maybe fewer, the genetic material of 14% of the population will be so diluted as to be unrecognizable.

> In a majority white and hispanic nation, niggers will disappear in 100 years....

LOL. Stupid half nigger

Ad Hominem. Typical low IQ uncultured, degenerate mixed-Orc post.

...

you are attracted to the white genes either way

if the average black person was an albino they'd be rightly considered sub-human

Race mixing is fine as long as the vector is going out of the advanced races into the lesser races. It is fine for a white man to breed a nigger or latina sow, but not good if the opposite (brown men impregnating white women).

those kids are fucking ugly

OP your pic is alright but fuck race mixing

...

...

>fat
Someone can't build mass, you jelly?

What's wrong with being pure?

thats a keeper

It's OK to be White, bruh

Nothing

It's OK to be mixed.

so the only way you can look good is get white genes

KEK

White skin blue eyes. Admit it youre attracted to the white features not thw black ones. So am i im latino. At least im self aware.

That's not a mixed race person, its an albino nigra.

why are you trying to pass for black?

didnt claim it was

Race-mixed people always take the worst features and traits of blacks.

you're american too wtf

maybe they cancel each other out.

Brilliant job mods

No basement dwelling faggot, if you left your moms home once in awhile, you'd learn there are an abundance of attractive people of many ethnicities.

Now, get back to your vidya games, NEET!

>its another "every nonwhite girl is pretty because she's white" thread

Im white I already won, shit skin, you will never be white no matter how many white women your daddy rapes

>starts losing and has to throw out ad hominems

Reminder that even they literally can't grow hair. Literally all mongrels have to keep their hairs less than 1.

Even these mongrel models with less than 30% African genes literally can't grow hair, it's an entire race of subhumans that don't have genes for attractive natural hair growth.

That may be true but take it from someone who lives in a real mixed race melting pot. The white is always king in attractiveness. Even if people dont realize it conciously they prefer white features.

...

Funny how even one ugly drop of nigger in the blood makes the result look like niggers, even with blue eyes. Those poor chidren have to live their lives being niggers every day for the rest of their lives.

Incel, the only thing you've won is free rent in mom's basement.

And. you have inherited a cucked faggo t culture.

sauce?

He has to pluck his eyebrows

The african genes just fuck everything up desu. And theyre apparently dominant and not recessive to boot.

you bring up moms basement a lot,

I get paid more, and dont get shot by cops
enjoy your halfican life loser

Maori does not equal african. They got their own thing.

Not even halfrican... half Dominican, half white.

Mixedrace children suffer from more health problems
ncbi.nlm.nih.gov/pmc/articles/PMC1448064/

Racemixing leads to outbreeding depression & pairings of non-complementary traits.

A massively well-funded study of over 100,000 schoolchildren found that “Adolescents who identify themselves as mixed race are at higher health and behavior risk than those of 1 race.” Indeed, even when controlling for education, socioeconomic status, and other factors, there is an across-the board higher rate of health risks amongst mixed race adolescents than mono-racial adolescents.
ncbi.nlm.nih.gov/pmc/articles/PMC1448064/

One study found that White-Asian mixes had a 2x higher rate of being “diagnosed with a psychological disorder, such as anxiety, depression or substance abuse.”
eurekalert.org/pub_releases/2008-08/uoc--baa081108.php

A study on Black-White mixes in agreement found that ”When it comes to engaging in risky/anti-social adolescent behavior, however, mixed race adolescents are stark outliers compared to both blacks and whites.” This holds true despite being raised in similar environments to mono-racial children.
msu.edu/~renn/RHE-_mixed_race.pdf

Often race-deniers and cultural Marxists will bring up Haldane’s rule, arguing that since races can mix and create fertile offspring, the genetic distance is not too great. Haldane’s rule is “when in the offspring of two different animal races one sex is absent, rare, or sterile, that sex is the heterogametic [XY] sex.”
nature.com/scitable/topicpage/haldane-s-rule-the-heterogametic-sex-1144

Indeed, although Black-White mixes are not sterile and males are not absent, males (the heterogametic sex) are more rare than females.

The argument regarding Haldane’s rule is also meaningless because different species in the animal kingdom can breed and still produce fertile offspring. The wolf (Canis lupus) and the dog (Canis lupus familiaris), the coyote (Canis latrans), and the common jackal (Canis aureus) are separate species yet can all interbreed and produce fertile offspring.

Black Americans are a hybrid race of around 22% White ancestry
genomebiology.com/content/10/12/r141

This 22% ancestry is the cause of multiple negative health effects due to genetic incompatibility. Indeed, consistent with Haldane’s rule, unmixed Blacks from Africa and White Americans do not have the same rate of birth problems that hybrid American Blacks have: “In 2005, the mortality rate for black infants was 4.4 times higher than that of white infants… African women who come to the United States and have babies experience the same low rate of infant deaths as white American mothers.”
t1nyurl.com/6tr9e6t (docs.google)

“Indiscriminate interbreeding between distinct forms, whether ‘species’ or markedly different races, is not generally beneficial. The defect may show in a change in the sex-ratio of the offspring, probably caused by the early abortion of members of one sex, generally the male in the case of mammals.”
amazon.com/Race-John-R-Baker/dp/0936396040

LTA4H, or “leukotriene A4 hydrolase” is found on chromosome 17. An allele of this gene increases the risk of heart attack (the #1 cause of death in America) in Blacks by more than 250%, but only 16% in Whites. The 30% of Whites with this allele have counteracting genes, while the 6% of Black Americans who obtained it through race mixing do not.

Hybrid vigor (heterosis) does not seem to apply to humans as we are already very heterozygous, at 0.776 [mbe.oxfordjournals.org/content/14/7/707.full.pdf] Compared to dogs for example at 0.401. [eebweb.arizona.edu/Courses/Ecol406R_506R/Garcia-Moreno1996-Wolf.pdf]

Although some argue that race mixing "averages out" traits and since average faces are considered more attractive [cs.brown.edu/courses/cs143/2009/lecture13.pdf] then mixed race offspring are more attractive.

However this is fallacious as it assumes we are designed for perfect symmetry, when in fact the magnitude of asymmetry is the correct measurement and this random component fulctuates, also called "fluctuating asymmetry" - so more honestly a lower level of asymmetry correlates with increased attractiveness, not symmetry.
beheco.oxfordjournals.org/content/15/5/864.abstract

But does increased heterozygosity cause lower asymmetry? A meta analysis of 118 datasets in 14 studies showed a very weak inverse correlation between the two, showing that increased heterozygosity has no beneficial effect on symmetry or asymmetry

The neurotransmitter oxytocin "makes people more co-operative, benevolent, loyal, generous and trusting of others. It is involved in the parent-child bond - new mothers and fathers have raised levels of oxytocin. Production also increases when people hug and when they have sex and, recent research suggests, when they receive psychological warmth." However, oxytocin has been alleged to "foster racism."
guardian.co.uk/technology/2011/jan/30/bright-ideas-oxytocin-hormone-racism

The study found that "intergroup bias that fuels prejudice, xenophobia, and intergroup violence… Which maybe modulated by brain oxytocin." This suggests that the instinctual desire to pursue the interests of one's own ethnic group to further ensure the existence of one's people is linked to racial bias, coinciding with the observation that diversity is a weakness, not a strength.
pnas.org/content/early/2011/01/06/1015316108

One study found that during the menstrual cycle when women have a higher likeihood of conception, racial bias is increased, especially when the likeihood of sexual intercourse was increased; "increased conception risk was positively associated with several measures of race bias. This association was particularly strong when perceived vulnerability to sexual coercion was high."

Race Is A Social Construct?
The Immune System: How Important Is Race?
>"If Nick Glasgow were white, he would have a nearly 90 percent chance of finding a matching bone marrow donor who could cure his leukemia."

Absolutely nothing

The reason that mixed-heritage patients are so hard to match can be found in the immune system. Different races have developed certain proteins, or markers, that are part of the body's natural defenses. These markers help the immune system determine which cells are foreign and should be rejected.

Are cells racist?
A match between two people who share more genetically in common significantly reduces the risk of the donor and recipient cells attacking each other. (READ: cells from people of two different races will attack and fight each other as though they are a virus)

The more people of different backgrounds who produce offspring = the more types that are harder to match.
Multiracial patients have uncommon profiles and since there can be many possible racial and ethnic combinations in multiracial societies, finding a match can still be extremely difficult.
m.phys.org/_news162659550.html

As an example, a White mother of mixed-race child would have more genetically in common with a random White person on the street than with her own child.
If such a dramatic and fundamental alienation from your own parents if not horrific enough, With a mixed-race child diagnosed with leukaemia, every member of the child's own family becomes an incompatible donor for a bone-marrow transplant, and finding a compatible donor is unlikely:

>One obstacle to finding a matching donor was her mixed ethnic background. Her father is black, with West Indian and Panamanian roots. Her mother is white, with Russian-Jewish roots. In addition, only 5 percent of registered donors are black.
nytimes.com/1996/04/18/sports/baseball-rod-carew-s-daughter-dies.html

Bone Marrow Transplants: When Race Is an Issue
>''Compared to organ transplants, bone marrow donations need to be even more genetically similar to their recipients. Since all the immune system's cells come from bone marrow, a transplant essentially introduces a new immune system to a person. Without genetic similarity between the donor and the patient, the new white blood cells will attack the host body.

The Race for Ancestral Genetics in Clinical Trials
>A seasoned cancer researcher would never set up a study in which all the ill patients were, say, Canadian, and all the healthy controls were Japanese. And yet cancer researchers risk making a similar mistake if they overlook genetic information that fleshes out what many of us like to think of as race or ethnicity, some experts say.

>Fortunately, awareness of how ancestral genetics might contribute to risk of disease and drug response in people has risen over the last several years. Studies that look directly at the problem are on the rapid rise, and this increased interest has biotechnology companies lowering the cost of tests that determine genetic ancestry, thanks to a little competition. However, experts have yet to decide on how to genetically define ancestry, suggesting examining anywhere from a handful to hundreds of gene variants.

>Not including information on the race or ethnicity of study volunteers could skew disease risks as stronger or weaker than they really are.

>"It occurs in about 20% of the African American population, and it means nothing. It occurs in about 6% of the Japanese, and it makes their risk six times higher [than that for white people]," Burchard said. "Something about being Japanese unleashes the wrath of the gene, and something about being African American attenuates it."

Sickle-Cell Disease
Sickle cell anaemia is a condition found almost exclusively in blacks, about 1 in 4 west Africans carry the gene for it, almost no whites do. Any whites who carry the gene most likely have a black ancestor.

As a result of population growth in African-Caribbean regions of overseas France and immigration from North and sub-Saharan Africa to mainland France, sickle cell disease has become a major health problem in France. SCD has become the most common genetic disease in this country.

Invasive species: Genes Are Destroyed With Admixture/Racial Mixing

yfw jason kidd has been a nigger all along

Extinction by hybridization:
>Nonindigenous species can bring about a form of extinction of native flora and fauna by hybridization and introgression either through purposeful introduction by humans or through habitat modification, bringing previously isolated species into contact. These phenomena can be especially problematic for rare species coming into contact with more abundant ones. Increased use of molecular techniques focuses attention on the extent of this underappreciated problem that is not always apparent from morphological observations alone. Some degree of gene flow is a normal, evolutionarily constructive process, and all constellations of genes and genotypes cannot be preserved. However, hybridization with or without introgression may, nevertheless, threaten a rare species' existence.

The Island Model with Stochastic Migration:
>It is supposed that the migration rate and the immigrant gene frequency are independent of each other in each generation, and each of them is independently and identically distributed in every generation. The treatment is confined to a single diallelic locus without mutation. If the diploid population is infinite, selection is absent and the immigrant gene frequency is fixed, then the gene frequency on the island converges to the immigrant frequency, and the logarithm of the absolute value of its deviation from it is asymptotically normally distributed.
The above implies that if you have two genes in some frequency in the immigrant population, under one way migration that frequency becomes the dominant frequency on the island.

...

>We investigated various cases of the island model with stochastic migration. If the population is infinite, the immigrants have a fixed gene frequency and the alleles are neutral, the gene frequency on the island converges to that of the immigrants.
What this means is that the genes initially on the model island, in effect, disappeared.

Evolution with Stochastic Fitness and Stochastic Migration
>Migration between local populations plays an important role in evolution - influencing local adaptation, speciation, extinction, and the maintenance of genetic variation.

>A number of studies have shown that when per capita population growth rate is treated as a random variable, rather than a fixed parameter, then directional evolution is influenced not only by the expected fitness of each phenotype, but also by the variance and other moments [23], [28]-[33]. This follows from the fact that, in a closed population, change in mean phenotype is inversely proportional to mean population fitness
plosone.org/article/info:doi/10.1371/journal.pone.0007130

Figure 1. The consequences of a negative correlation between fitness and immigration rate:

All of those models are done with products. There's no african hair that looks like that without apparatuses. Also, hair is no as forgiving to women as it is to men. A lightskin mongrel can't grow more than 3 inches of hair without looking absolutely ridiculous.

Anyone that breeds dogs or horses knows that's just an out right lie.

The more pure bred, generally equal more potential health problems.

In fact, that's how DNA was discover when royals wanted to figure out why they were having so many genetic issues from inbreeding.

Figure 3. The relation between variance in immigration, selection, and in an island-continent model:
plosone.org/article/fetchObject.action?uri=info:doi/10.1371/journal.pone.0007130.g003&representation=PNG_M
>bottom-right in picture.

>The curves show the change in mean phenotypic value assuming a mean phenotypic value as decided by a population's selection.
>The variance in migration is shown in descending value on the curves.

Though the mean rate of migration is the same on all the curves, it is clear that the the island can still get close to fixation of the phenotype favoured there, so long as the variance in immigration is high.

So for this figure, assuming that migration is an indefinitely persisting condition, migrants will prevent the local island favored phenotype from remaining intact, as they are essentially working against selection.

Lol

...

The models/simulations in these studies are based on understanding evolutionary genetics, on how migration influenced evolution, which makes them excellent sources for metaphors on the effects of modern immigration rates in human populations.

Allopatric speciation or geographic speciation is speciation that occurs when biological populations of the same species become vicariant — isolated from each other to an extent that prevents or interferes with genetic interchange. This can be the result of population dispersal leading to emigration, or by geographical changes such as mountain formation, island formation, or large scale human activities (for example agricultural and civil engineering developments). The vicariant populations then undergo genotypic or phenotypic divergence as: (a) they become subjected to different selective pressures, (b) they independently undergo genetic drift, and (c) different mutations arise in the populations’ gene pools.[1]

The separate populations over time may evolve distinctly different characteristics. If the geographical barriers are later removed, members of the two populations may be unable to successfully mate with each other, at which point, the genetically isolated groups have emerged as different species. Allopatric isolation is a key factor in speciation and a common process by which new species arise.[2] Adaptive radiation, as observed by Charles Darwin in Galapagos finches, is a consequence of allopatric speciation among island populations.

Reproductive isolation - Sexual isolation by behavior or conduct
Even where there are minimal morphological differences between species, differences in behavior can be enough to prevent mating. For example, Drosophila melanogaster and D. simulans which are considered twin species due to their morphological similarity, do not mate even if they are kept together in a laboratory.[3][12]Drosophila ananassae and D. pallidosa are twin species from Melanesia. In the wild they rarely produce hybrids, although in the laboratory it is possible to produce fertile offspring. Studies of their sexual behavior show that the males court the females of both species but the females show a marked preference for mating with males of their own species.

Just imagine what a few extra years of separation could have done for certain human populations…

Sup Forumstards are still in denial about basic science and common sense

This board is full of stormweenies who reject reality for 'muhh white race'
