The problem is though they are still Muslims in good standing. When you look at what is going on in Indonesia and the killings of millions of African Christians and animists, the killings of millions of Hindus in India and Pakistan, it becomes apparent that in Islam, violence is tolerated. In other religions a priest or minister or rabbi or layman that goes overboard and promotes mass murder claiming religious reasons would be ostracized or excommunicated. Bin Laden and all the killers are Muslims calling for Jihads and no one can say they aren't real Muslims.
