I'm going to relate this to porn, because it is as truthful as can be and is the exact same situation as what your dumbass is trying to prove. The functionality of a white man's dick is far inferior to the functionality of a black man's dick, but that doesn't make porn producers use them any less. Most people who watch porn don't watch it for how much agony the girl is in, they watch what looks best to them.
Moral of the story, UD=white man, human=black man.
That's possibly the dumbest thing I've ever read.
