Directly provoking a crazy person is one thing. It involves a direct confrontation with said person, and then directly antagonizing them into a given action.
Making a movie that you dont have to watch is a provocation only in the minds of those provoked. Or are you saying any Muslim who responds poorly to this movie is crazy?
The movie is provocative; I surmiss the producers had no other motive for its production. Of course they cannot be held responsible for the reaction - criminally or civilly - and they have every right to produce it. And, the Federal Government has no authority to surpress it.
Of course those demonstrating in the street are not (all) crazy; no more so than any participant in any massive demonstration or those fans (for fanatics) who cheer at an NFL game. Go to an NFL game in Philly and wear the colors of the NYG or Dallas Cowboys. The reaction of some Philly Fans will be loud and profane; common sense suggests the Philly Fanatics won't ignore it and will respond to the provocation. Common sense also suggests that the majority of Eagle supporters won't.
Those who attacked our diplomats are not crazy either. They are criminals who believe they have the right of enforcement, using extreme violence. Common sense suggests you do not poke a tiger with a stick, stare down a bear, grab an eagle from its nest or insult the religion of a Muslim. Of course not all Muslims will react violently; but some will and have in the past killed innocents as well as provocateurs.
Why would anyone do so? Why would anyone defend them? And why would anyone but a partisan hack suggest a critique of someone who provokes others is a defense of the few who act out violently?
