It doesn't seem like so long ago that the world wasn't "shocked! I say shocked!" when a comedian, rock star, etc... had a little anti-authoritarian bent. A big fuck you to whoever was in charge, to whoever the powers that be were, has been part and parcel of even the wimpiest pop culture for decades.
I really find it creepy that it's big honking major controversial news when some rock stars... any rock stars... question Bush's authoritah.
