I wish people would just realize there is no official cult of all self-proclaimed "tribal people" coming to get them that gather around talking about their next plan to oppress non-whites. Everybody in the world is tribal. Even if they don't understand racism, they are 100% no doubt tribal. Racism is realizing the cultural differences and stereotypical associations between races of human beings. They're in the back everyone's mind when they interact with another person.
racism refers to a pretty specific kind of prejudice that is learned because people rationalize it and accept it. if you're socialized in an environment where diversity is commonplace and those around you are not tribal, you probably won't be tribal, because while the pattern-forming heuristics that fuel the first hints of racism are a product of nature, prejudice is
always a matter of nurture, because it's a world view that has to be adopted and reinforced and not a simple instinct. it doesn't really have much to do with complex structures like culture, it really is as simple as the way someone looks; that's more than enough for our minds to start making distinctions that might not even exist.
