Is the rage over the Mohammed cartoons manufactured?

Consider the following:

• The Mohammed cartoons were originally published in September 2005 in Jyllands-Posten, but it took 5 months for the issue to flare up internationally, during which the following things all happened.
• Apparently the Mohammed cartoons were published in Egypt (a Muslim country) in October 2005 without a peep of dissent. And this was during the Muslim holy month of Ramadan.
• Some Danish Muslims toured the middle east, showing the original 12 cartoons, but added three pictures of their own, one depicting Mohammed as a pedophile demon, one a photo of him with a pig's snout and one showing him being sodomized by a dog!
• One of the three extra pictures, the pig snout one, was originally a picture of a contestant at a French pig squealing contest!

I also find it suspicious that embassies in the middle east, such as Syria and Iran, were torched. Many of the countries concerned are dictatorships with high degrees of social control being exercised by the state. I find it hard to believe the riots would have been allowed to get so far out of hand had they not had some tacit support from the authorities.
