As I said before, Islam is not a monolithic religion. One can't condemn the whole religion on the basis of what some of its members do or don't do, any more than they can condemn any other religion on the basis of what some of its members do or don't do. To do otherwise is prejudiced.

Some Imams speak out about things like stonings and other atrocities committed by other Muslims, and they and the Islam that they practice should not be judge according to what other Muslims do or don't do, because even when they speak out about it, they still have no way to make it stop.
