@inthegarden makes a really good point about racism or feeling uncomfortable around others not like ourselves, and that is that kids learn this early, and it isn’t taught the way parents think it is. I think kids are born without any prejudice per se, put a bunch of toddlers together who are all different and you won’t see the kind of issues you would when they get older. Kids pick up their attitudes from their parents, and it has little to do with what the parents ‘teach’ them, ie “the only race is the human race’ or “that little girl over there simply has dark skin/eyes that appear slanted/etc”, kids pick up from the parents how comfortable they are with people who are different. If the parents only hang around people who are the same as themselves, that sends a message (and obviously, for a lot of people that may be because that is the nature of where they live, how segregated things are), the old expression is attitudes are caught, not taught, and the old 'do as I say, not as I do” doesn’t work. Kids pick up on a ton of subtle (and not so subtle) clues from people around them, especially parents and other family members.
