Anyway, I think Muslims are already idol-worshippers, and don't know about their natural inclination.
A person who kill another in Muhammad's name, then he is idol worshipper.
Take the Danish cartoons, there were a lot of violence and damages to properties. Even a Syrian nun was murdered because of their anger over the cartoons, but this nun had nothing to do with those satire drawings. And how many people have threatened to kill the cartoonist and publisher?
All these people who reacted like this, are all idol worshippers. They have treated Muhammad like god, accusing people of blasphemy who weren't involved in the cartoons.
The annual pilgrimage to Mecca is the signs of millions of idol-worshippers.
