I clicked your link, read the professor's "excuse", and was disgusted. An academic should be ashamed to blame society's ills on innocent men because of their skin color. BTW, calling the black dancer a "hooker" is perpetuating a stereotype, isn't it?
You should come over to the DUKELAX threads that are ongoing; I have been stunned at some of the stuff they are involved in.
And people wonder why this country is going to hell?
