How Radicals Respond to Satire

Looks like radical Muslims are attacking free speech on the Internet: Michelle Malkin's Denial of Service attack on her website.

The radicals are all bent out of shape over those Prophet cartoons, so what do they do? Riot, burn buildings/cars/whatnot, and hacking. I can understand their displeasure over the satire of their Prophet, but why commit destruction? This has all been orchestrated by radical imams from Denmark, which they also made up cartoons of the Prophet, one of which made him out to be a pig.

Somehow, I can't see Christians rioting over insulting images of Jesus Christ or the Virgin Mary.
