The majority of the planet involved in the coalition who fought the Nazis were biological essentialists.
The problem is the insincerity of the idpol left in acknowledging biology is a factor in humans and conflating that with naziism.
For instance you've got the problem of Pakistani populations in the UK and the endless whining over how they are oppressed, then using economic stats and social mobility stats to demonstrate it, already knowing they've taken off the table and labeled as Nazi things like noting;
"They have four times the rate of genetic disease and are less intelligent. Ofcourse they're not as productive or well off.".
That aspect in itself is rooted in sociology; Over half of them marry their cousins and that's been going on for generations now. Within two generations that's a level of inbreeding equivalent to having children with your half-sibling, and doing it again after that results in a full sibling level inbreeding ratio in terms of genetics. They've been doing it 80 years, or three or four generations. You may as well be crying and calling everyone Nazis for acknowledging Habsburgism is a thing.
This also impacts the level of violence the population produces and so on.
But talking about any of that is verbotten. Better we ignore reality and institute a kakistocracy so as to have the superficial appearance of equality.
"Do we go with someone competent, or fulfill our quota by hiring a Habsburg with no chin? Hmmmm."
