@Adirondackwannabe, I don’t think there’s any “probably” about it. The vicious murderers are definitely worse than the guy who mocked a 7th-century cultist. And, not having seen the movie, I can’t comment on whether or not the person who made it is an idiot.
I do think there is plenty to criticize about Mohammad, a warmongering cult leader who had sex with a 9 year old girl, and I think it’s tragic that publicly pointing this out often results in an angry fundamentalist mob killing people halfway around the world. Nobody should be silenced from criticizing or mocking Muhammad because of these actions.
At the same time, “crazy Islamic fundamentalist mob retaliation” is, at this point in history, a known quantity. And I have to say I’m opposed to this kind of cavalier attitude that some free-speech advocates have about it. In one sense, making movies like that strikes me as poking wild animals with a stick. At a certain point there is the pragmatic question of “is it worth it to deliberately provoke Muslims with a mocking portrayal of Muhammad if it means someone is probably going to die because of it?” And I don’t think there’s an easy answer to that question.
