Here is my response to this article:
If Joan Rivers apologized every time she offended or hurt someone through her often crass sense of humor she would open a real can of worms. The only way you could corral Joan Rivers is to put a chastity belt on her mouth! It's 'what she does'. Comedians wouldn't be funny if they were always 'politically correct'. Vulnerabilities and weaknesses in life feed the absurdity of a comedian's humor. I'm not saying it's right or wrong, it's just the nature of the Rivers' beast, so to speak.
