Well, in the first place, this sounds like a hoax, so it’s all a moot point.
However, I seem to remember a couple recent US Olympic teams full of “African Americans” who got their a$$e$ handed to them by European teams.
As far as the “baskets at 8 feet” crack, I’m not buying it—but just curious—do you make similar blanket statements about, say, black people’s intellect, literacy, or work ethic?
Let me give you a hint-IT WAS HUMOR!
