Ross Douthat takes measure of the South Park vs. Islam controversy. Excerpt:

Across 14 on-air years, there’s no icon “South Park” hasn’t trampled, no vein of shock-comedy (sexual, scatalogical, blasphemous) it hasn’t mined. In a less jaded era, its creators would have been the rightful heirs of Oscar Wilde or Lenny Bruce — taking frequent risks to fillet the culture’s sacred cows.
In ours, though, even Parker’s and Stone’s wildest outrages often just blur into the scenery. In a country where the latest hit movie, “Kick-Ass,” features an 11-year-old girl spitting obscenities and gutting bad guys while dressed in pedophile-bait outfits, there isn’t much room for real transgression. Our culture has few taboos that can’t be violated, and our establishment has largely given up on setting standards in the first place.
Except where Islam is concerned. There, the standards are established under threat of violence, and accepted out of a mix of self-preservation and self-loathing.
This is what decadence looks like: a frantic coarseness that “bravely” trashes its own values and traditions, and then knuckles under swiftly to totalitarianism and brute force. … [I]f a violent fringe is capable of inspiring so much cowardice and self-censorship, it suggests that there’s enough rot in our institutions that a stronger foe might be able to bring them crashing down.
