@Bernard He KNOWS the answer is race. He just really wants it not to be because he's been taught everyone is equal in all ways and racism makes him evil. He knows.
He wants there to be some gotcha. Some "uhm, acktshually..." science answer or rhetoric. But he knows. We all know.
My mom and sister live near a grocery store they won't go to. Walking distance to it. It's near a bus stop niggers use so it's staffed by and filled with niggers, even though it's in a White neighborhood. I ask why they don't go there (I know, we all know) and they say "Oh the people in there are just... it's sketchy."
And if I were to suggest it was the niggers, that would be a bridge too far. My mom, maybe. She's old enough. My sister would lose her fucking mind. But she still knows. She doesn't go to nigger stores or the nigger part of town.
We all know. We just don't want to be evil and all our institutions said racism is the last true evil.
