I think if you want to understand racism, you can't understand it as the failure to have certain pieces of knowledge. Racists generally aren't unaware that people experience suffering when they're held down or held back from their appropriate station in life.

What racists generally believe, if you're trying to be maximally charitable to the views of racists (ugh), is that human suffering also comes from pushing people into societal roles that are above their station. The individual so pushed suffers, and society suffers for having "the wrong people" in important roles. For instance, that's the view that held that slavery for Black Americans was good for them.

I think a racist in that strain would play the Detroit game and not be convinced, since the game likely doesn't address that position at all.
