Afaict, a good part of racism comes from the fact that human brain automatically labels people different from you as enemy. I assume this was a very useful strategy for millenia, if you saw a person not belonging to your tribe/nation that probably meant armed conflict a decent chunk of the time.
This applies to any kind of difference: clothing, culture, neurodivergence etc. I live in a country with zero racism against black people (all the racism is reserved for immigrants which only differ by culture, not color) yet you can tell black people are still a bit left-out in many social settings.
Due to black population being very low, people rarely ever see a black person here. When they see one, for the brain it's an unknown/unfamiliar, and that means potential danger at the subconscious / first impression level. To put it simply, people get weirded out. Ofc, once you get to know them that goes away.
(This is not to condone conscious racism: goyim, plantation workers and all.)
