Maybe it's just the fact that I'm a middle class white guy, but after seeing that video, I'm not terribly upset by this. First off, I'd love to hear what "gentle heckling" was being thrown at Richards. Every time I've heard heckling, especially alcohol-fuelled heckling, it's been anything but playful and gentle. Also, at the end of Richards' rant he makes comments about words still having the power to shock and offend, which leads me to believe that he may had a bigger agenda than just race baiting. I never bought into the "it's okay for me to say a word, but not you" practice, and I think that in some part (perhaps completely by accident) Kramer is making us contemplate that. I, as a goyim, could never get away with making the same jokes that Borat, or whatever the hell his real name is, is getting millions for making. That hypocrisy has always bothered me.
PS: Feel free to call me honky or hunky in any replies.
Cheers.
