It was Comedy Central (viacom), not SP that caved.
The Cartoon Wars shows were written to illustrate that. Pretty smart, though I really didn't like the crapping on Jesus part.
And what have Parker and Stone said about that since it happened? < crickets >. They're not outraged. At most, they're relieved. They conned you and the rest of their fans, kept the Muslims happy, and got Comedy Central to take the heat for it.
They're back to cranking out insults of everything but Islam. Don't want to shut off the money spigot.
