Give me a break - by all indications, the author of the video made it for his own religious reasons, because of his own delusions, rather than as some kind of enlightened critique, which explains why it's, y'know, so extremely crude. He made his video specifically to cause maximum insult to a culture: that doesn't put him anywhere near the lunatics who would kill diplomats over an insult, but he too is a lunatic. I'll defend to the death his right to say it, but it's hard to support it in any way.
Also, I don't know what you meant by it, and I apologize for being presumptuous, but your "people in backward, poorly governed countries that could never have invented the Internet" suggests an image of cultural superiority, which is an awful thing to create in response to the actions of a violent few.
