Racism is not primarily a psychological phenomenon, but a system of disparities that can maintain itself even if most people want to be "fair" or don't actually have any individual bias. It also requires prejudice + power. I think what you are asking about is more "bias"
Racism has absolutely nothing to do with whether your group has power. Only the overtly racist minorities and their misplaced guilt ridden coddlers make that argument.
i think there is a fringe "racist" group of black people. its a different type tho. still bad, but justified reasoning since you know. we enslaved them for 100s of years. white people tend to have a higher racist count, but more of them are just really really stupid.
