It seems to me that these Christian fundamentalist zealots who are offended by what they see on television suffer from what I call "False Piety." That is, they believe that their religious views are the correct ones, and everyone else is wrong and going to "The Bad Place." I wouldn't be surprised if those practicing "false piety" wound up in "The Bad Place" themselves.
As for television corrupting children, well there's obviously a consensus that no child should be banned from watching television, so I won't argue that point. Seriously though, there isn't really much on television worth watching. In fact, I stopped watching regular television plus my DirecTV once the novelty wore off. After all, why watch a network's choice of programming when you can get DVDs of whatever you want to watch whenever you want?
Back to the title of this thread, I'm surprised the FCC didn't get any complaints that the Simpsons shows people who are just plain mean.
