Ricky Gervais, a comedian I usually find brilliantly funny, wrote this piece about people being offended at jokes, primarily his. I would have been more impressed if he'd just written, "Hey, if you don't like what I do, don't watch me." Instead, he tries to blame "political correctness" and people who aren't smart or hip enough to understand what he's doing.
As I think I wrote here recently, the term "politically correct" seems to me to becoming pretty meaningless since so many people use it with such different definitions. One which irks me is when people employ it in to try and deflect or suppress criticism. Another is when their definition is that they should be free to say whatever they want without anyone disagreeing or making personal judgments about them.
My concept of Free Speech includes your right to make racist remarks or jokes but it also includes my right to say I think you're a racist. And my umbrage might not be because you're being "politically incorrect." It might be because I think you're a racist. Actions have consequences and so does speech.
Like I said, I usually find Gervais quite hilarious but that doesn't apply to every comedian out there. More and more, I hear the ones who don't evoke the laughter they seek blame their audiences for being too "politically correct." Well, maybe it's that. But maybe they just aren't as funny as they think.
