i still would like to know what exactly was said to him to begin with. sure he's an eccentric man and whatnot, but part of this story is missing, and it's fairly safe to blame the media. while i admit he went a little too far, notice how you could still hear people laughing as he was ranting until "that was uncalled for"
if some white guy heckled a black comedian during his act, and the comedian made similar remarks in retaliation, it would be no big deal.
either way, in my opinion it's about time people grow up and let things go. it's like when you were a little kid and someone called you a "stupid poop face." it was said to offend you, and you took the bait and made a spectacle out of it.
