Isaac Hayes recently quit his role on South Park, a sitcom on Comedy Central. He said that the show crossed a line when it came to religion, and that he couldn't stomach it anymore.
I understand what he's saying. I hit that limit with the show myself, back around 1998-99. Originally, I found it humorous. However, after watching a couple dozen episodes, I noticed a trend. The writers were trying less to be humorous and more to be obscene. I'll try to explain my rationale:
Lines in sand exist on television and in the movies. Many things are taboo, or were taboo. A lot of modern tolerance can be said to be found as a result of efforts in the name of entertainment. We sweep the stuff out from under the carpet, as it were, and we become better for it. Examples might include All in the Family, or Lord of the Flies, or Mississippi Burning, or Boyz 'n da Hood. These shows/movies were vulgar, crude, at times obscene. However, they explained a part of our society that needed uncovering and explaining. In other words, the shows were obscene to make a point.
South Park, on the other hand, appears to have a different outlook. It seems to me that the MO of the writers runs something along the lines of "let's be as crude, vulgar, and offensive as we possibly can, but we need to think of a reason to justify that crudenes." And so they'll come up with a "message," much like those public service "don't fight each other" messages at the end of He-Man or GI Joe, so that they have plausible cover for their shows. In other words, they have a point as an excuse to be obscene.
Now, do I think it's wrong that the show goes like that? I don't care. If that's what the censors will let them do, and people continue to buy advertising space in their time slot, then I won't say they can't do that. Nor can I say the stuff isn't funny. Indeed, it most likely is to a certain portion of the populace, as they watch the show. I can say that it's not funny to me, because I don't think they work hard enough to make a joke, but I think that's the case with many comedies.
So in conclusion, Isaac Hayes quit. I don't blame him. The creators of the show glibly note that he didn't have any problems cashing the checks when they made fun of other religions, which I thought was inappropriate and unnecessary. I don't find the show humorous. Other people do. I would prefer writers and shows that work at creating jokes, and not resorting to crudeness just to save effort.
