Fine, he lased out....whatever. There was no mention of hanging and "upside down" has absolutly NO implications of hanging or lynching. Hell, you cant hang somebody by the neck upside down.
He says, "50 years ago you would have been upside down with a fork up your ass." Sure, that probably is a racist comment....but it has NOTHING to do with hanging.
And, you have no idea what these characters were saying to him before the video started. They could have been yelling anti-sematic cracks at him. I say, if you weren't there, don't judge. It seems like the first few times he said the N word everybdy in the audience laughed. I think they left out of fear or awkwardness. Hell if LAUGH! let him perform again the next night on the exact same stage, they must have had SOME reasons to keep him there.
Disrespecting a performer is uncalled for...Richards (although I am sure there were more civil ways to handle it) handeled it his own way. You don't go to Broadway and sit in the back and scream "your voice sucks!" do ya? And if you did, your ass would be out on the street in less than 30 seconds. Its a comedy club. It's a rude place as is, if you can't show respect for a well known comedian your black or white or yellow ass should be yanked out anyway.
