I mentioned once before that much of the black angst towards whites hinges on the fact that they can't seem to find a word identifier for whites that really upsets them. Nothing really works! Think about it.
I known it sounds simple and childish. But there is a lot of fact in the statement.
"Racist"
Imagine a white person approaching a random black person and calling them a "N". Now reverse the roles.
You have your word......
