Bob Crane, the notorious former Nixon aide and convert to Islam, says so in a revealing new piece. He's against such violent protests, mind you, and he thinks Geert Wilders, the Dutch politician who is making the film, is just trying to provoke such reactions (Wilders explains himself eloquently here and here.) But he does think they would be "natural." "Challenge and Response: The Case of Islamophobic Wilding," by Dr. Robert D. Crane of The Center for Understanding Islam at "The American Muslim."

Muslims Against Sharia denounce Crane's perverted interpretation if Islam. He does not speak for Muslims. Moderate Muslims will NOT have a violent or angry response to a depiction of the Prophet, however distasteful that depiction might be. Muslims who do react violently, are Islamofascists and do not represent all Muslims.
