If a Christian group was to commit atrocities on the level this muslim "religion" has done the Pope himself would be on TV condemning the action to a worldwide audience.
And who is the Muslim equivalent of the Pope, exactly? Also, the Pope only represents one section of Christianity, which contains a moderate-extreme axis within it too. It's the same with Islam, except that none of the sects have a leader on the same scale as the Pope.
I think Islam needs a central leader. You have the Dahli Lama and you have the Pope. If Islam had one leader, this might get the radical terrorists under control. On the other hand, the non-crazy Muslims might all turn crazy.

If someone made a cartoon making fun of Jesus, would Christians be starting violent riots (that resulted in four deaths so far)? I would be angry, but I would not go around killing people or holding signs threatening people. And if I were going to cause trouble, I would go to the main building of said media company, not the embassy of that country. I still couldn't take a guess on what percentage of Muslims are crazy terrorist sympathizers, but it's got to be higher than I originially thought.
