Feelz aside

why should incest be illegal or frowned upon, again?

>inb4 mutant kids
sex, not procreation
>inb4 le degeneracy
so is alot of stuff that is legal and accepted

lmao you didnt even try. Off yourself.

is that supposed to be an argument?

Because it NEVER starts between adults. incest is always a pedo and a child.

since when?

Trust me or find your own facts. We both know you won't do either of those things :)

not an argument

First off: Families usually don't tend to function that well after say the mother starts fucking one of the kids due to the fact its clear she prefers (insert child here) over the others and 9/10 the father is not going to appreciate being cucked by his genetic offspring. This inevitably results in broken families which if you want to see how bad that is, just look at any ghetto community in America.

Second, though it does take generations for the mutations to set in, in societies where incest is practiced it does eventually lead to high mutation rates along with being more aggressive and uncivilized. If you want an example of this just look at Pakistan where they are having a national crisis over the fact most people marry their cousins which is leading to some interesting genetic side effects.

So in conclusion, stop asking to bang one of your female family members and actually attempt to get a girl who isn't related to you by blood.

what if its a widow with just one kid?

Oh. I thought you guys liked boys.
