Here's the money quote from a great interview with Matt Stone, Trey Parker and Comedy Central's Doug Herzog on the refusal of Viacom to allow even a simple image of Muhammed on their cable channel:
Matt and Trey learned the ridiculous reality that they can show Jesus defecating on George Bush, but they can't show Mohammed. Matt said, "That's the point. It's open season on Jesus." Trey added, "Yeah. You can do anything you want to Jesus."
Violence works, in other words. As long as corporate cowards like Viacom reward it.
