"I'm not biased only against Black people, I'm actually biased against anything that is sufficiently non-white" (in this context, since we're talking about a study of conventionally WASP-y vs. black names) is not the slam dunk you think it is. And it's still racist.

> You assume a racist motive in your scenario

No, I don't assume any motive whatsoever. I'm talking only about actions.
