Anyways, on the bright side, it means that there is an underserved market here for black women. That's gotta be useful somehow, I guess?
We can argue dictionary definitions, and of course I would concede, but in the real world, calling someone a racist has additional connotations. I don't think a subconscious, genetic attraction to your own race, as shown by all the evidence of all races preferring their own race, deserves the label of "racist", with all the guilt and shaming and "wrongness" that comes with that word.

It is like the ancient Greek comedies all over again.
Why dont we make the attractive people HAVE to sleep with ugly people first?
