I don't want to get into the backstory on this one. But I did want to link to this article. As I commented on a friend's posting of it, "I very rarely enjoy anything on Jezebel. But this was actually good."
The key, I think, is realizing that comedy is just another form of communication. Because comedy (often) works by playing with language, we should cut it some slack when it's facially offensive. But that just means we need to look closer for the underlying message. And if the point of the joke is to be nasty (rather than, say, to caricature and ridicule nastiness), the fact that it's a joke doesn't make the comic less of a jerk.
