Comedy, is not for oversensitive tight asses, who think fat jokes are anti-obesity. Or gay jokes are automatically homophobic, or religious jokes Christian, Muslim, whoever else, that person is some bigot towards that religious group. Comedy, is exactly that, a way to critique life and people in life. Including groups and even talk people and groups and their shortcomings. Not to say that every member of whatever group, has some clear flaw, but to point out humorous flaws about members of certain groups and even flaws that some groups carry as a group. The political correctness movement of the 1950s, didn't want to hear jokes about sex, religion and sure as hell didn't want to hear adult language. Especially since they still saw adults as kids for the most part who needed to be babysat.
The political correctness warriors of the 1950s, didn't want to hear jokes about sex, because they believe sex didn't exist or something. They didn't want to hear jokes about narcotics, because they were on alcohol or marijuana highs and believed narcotics simply didn't exist. Lenny Bruce, challenged the political correctness establishment in America and paid a hell of a price for it. All he was about was free speech and talking about issues and using adult language even that most Americans, at least outside of the Bible Belt used anyway, but did it in public. Did it in a way that simply wasn't done back then for the most part and didn't become mainstream at all, at least until the late 1960s. He was a true American, because he was an individual who felt the freedom to be himself. And express how he felt about issues even in public.
