Never, and that's the difference between the Muslim world and Judeo-Christian world. We are free to protest the actions of others. We're free to protest the war and free to protest the war protests. The Muslim world has only the duty to protest the action of others. It does not have the freedom to examine itself and express any self criticism (e.g., Salman Rushdie, anyone?).
Christ came to transform the religion corrupted by Pharisees into one of goodness, love, and service. For those efforts he was crucified. The Muslim world has had no such Messiah. We can only hope that a modern day Luther will appear for the Muslim world and help free it from the mental shackles it has imposed on itself....
