Continuing >No group is as cohesive as they seem from the outside.
This is a meaningless sentence, because it doesn't make any clear point at all.
Humans have always organized themselves in tribes, which are connected by blood.
They will favor those within the tribe to those from without, because that is simply an evolutionary strategy to spread genes that are most similar to them.
What do you think a nuclear family is? Or even a nation-state (the kind that doesn't really exist anymore nowadays)?
This is really how every single society has worked in the past.
That there are disagreements and conflict within a tribe is not a contradiction to that.
Ideally men compete with each other in a tribe to gain rank and privileges while at the same time helping the tribe overall (eg they can compete about who hunts better in a hunter-gatherer system). Of course that doesn't always happen.
But you really have to keep your eyes shut to not see how tribalism has influenced history.
Look at jews, it doesn't matter if they also "jew" each other sometimes, they DO see themselves as a group and act as such. They will favour their own to goyim which is why you see that the elite is filled with jews, and that they receive disproportionate credit for their achievements in any field.
WHO is pushing cultural marxism in the US? Who invented communism? What do Marx, Lenin, Trotsky, 90+% of members of the soviet central party, most writers and CEOs in entertainment, positions in finance, jews were a minority there until a century ago.
Who writes the scripts for the degenerate modern movies, who writes articles of fake news, no matter where you look it's always a group of jews, and I encourage you to actually look for yourself, every time. Look up the names of writers, directors, bankers, CEOs and you will see that america is virtually controlled by jews.
Who started the feminist movement? Anywhere you look where there is division between westerners, you find jews.
