A naive question.
In this politically correct world where certain foods are banned, certain words are banned, certain ethnic groups are to be identified by certain titles (Asian-American, not Chinese. Native American, not Indian, etc.), and your sexual orientation (only if you're gay, of course) is never to be looked down upon or questioned as to its morality or lack thereof...
Don't you think something like this should zero itself out? I don't think Isaiah should have to apologize, frankly. The "protected" people should be able to say whatever they want to each other. It's the white, middle-class Republican women like myself and the Sage that shouldn't be able to criticize or make fun of a black man for his politics (i.e. Al Sharpton or Jesse Jackson) or a gay man for his lifestyle (pick one). But put the two guys together and they should be able to do whatever they want.
