Teachers spend most of schoolday not discussing racism. OK, but we're still not talking about a remotely even amount of time. Not to mention that teachers are authority figures, have an extremely captive audience, can punish incorrect opinions, and have near total control over the material children are exposed to during the school day. They make people feel sense of community, common enemy (!), purpose and feeling of strength. I think that they are immoral and wrong, but that does not mean I am going to deny emotional appeal it has especially on young. So then you believe there is a defect in humans which results in them having a natural susceptibility to these ideas in particular, and as children humans need to be carefully insulated from these ideas or it will be very difficult for them to reason their way to other ideas as adults. Is that a universal human defect, or one that is found particularly in some class of human?
