Fair enough, good examples, although you left me even more confused than ever. On the one hand you're supporting the right to be downright offensive and parody black people for amusement, but you're somehow taking the moral high ground with sexuality? Yah...ok.
I used Amos and Andy as extreme example of censurship on the grounds of political correctness, but then to allow pornography as acceptable. I find Amos and Andy no more offensive than say Dukes of Hazzard or The Andy Griffith Show. I could give you so many more examples of stereotypical satire.
The Smothers Brothers show back in the day is a great example of extreme political satire programming that would never make it to a major network today.
