I'm not sure why anyone is surprised by the Muslim reaction to someone condemning their religion. Islam is a religion mired in the intolerance of the 11th century; at least so far as orthodox practitioners of the religion are concerned. Anyone who knows Christian history will recall that most Christians were a pretty intolerant bunch until recently. Muslims are really no different. And Locutus is right. In the age of the internet all religions are going to be mocked; especially those most likely to react violently to mockery or criticism.
