That thread is just baffling.
People are using ever possible explanation to justify why it's cool to say "all black women are unattractive" or any number of weasel-word versions of the same thought. I find myself less wtf about it if I approach the discussion from a "man want smash" standpoint, though...but that's probably because I'm a man, and I want to smash, heh.
Everyone's an anthropologist and an expert on psychological/biological/hormonal aesthetic science when it comes time to cut black women down!
