Kathy Griffin Reaction

So Kathy Griffin won some stupid award for doing nothing and insulted Christianity in her acceptance speech. I saw a clip of it here, which is followed by some interesting dialogue. One guy argues (correctly, I think) that had she said "Suck it Muhammad", then everyone would have been offended. But because it was Jesus, Hollywood doesn't care. Pretty interesting debate. I know she was just joking or whatever (and the actual joke is funny), but shouldn't there be limits on what is acceptable in humor? Our culture, or really those who are shaping our culture, don't care about God and it shows. JM
