Except that doesn't scare them. They've created a whole strategy around getting their brains blown out for the cause. In fact, your statement is exactly what they want us to say. It allows them to justify, in their minds, doing what they're doing.

Obama understands that this outburst of anti-American protest has nothing to do with the film in question. That's just a convenient excuse for radical groups to instigate new attacks...and on 9/11 of all days...what an amazing coincidence.
Romney, on the other hand, has a strategy of trying to put out fire with gasoline.
Art has a double face, of expression and illusion.
