Both cases are very abhorrent examples of racism. Perhaps it is convenient to justify tribalism as a “[…]fundamental human survival instinct” but that’s the same useless lizard brain justification that people use to justify unacceptable behavior, namely sexual assault. We’re so far past being tribal hunter gatherers so there’s absolutely no point in trying to 1. Predict how people behaved back then 2. Use animal behaviors to justify how present day people behave 3. Apply these bad inferences as excuses to the norms we have in place today. All forms of racism are unnatural and prejudices might “seem” justified if you’re an animal, but the prejudices we have were obtained during our modern day lived experiences and not some deeply in-grained natural response. So no, you can’t just say racism is some kind of animal adaptation that we maintained through prehistory.

You're conflating possibly offensive human behavior with clearly evil fascism, thus downplaying the worse evil. That is not acceptable and I think you should stop it.

I think you should stop trying to justify racism on pseudoscientific grounds and just making up silly unfounded excuses for such behavior.
