“Within Islam, these lines of division are many times more acute. Ahmadi Muslims are considered impossibly heretical by most other followers of the Prophet, and Ismaili Muslims are looked upon askance in many quarters as well, but the rivalry between Sunnis and Shiites (which also conceals numerous poisonous rifts between different interpretations and leaderships in both camps) has become one of the most toxic phenomena in the world today. On Web sites that offer advice to the devout, Sunnis and Shiites ask their imams and ayatollahs whether it is permitted to take the life of a member of the other sect. On American campuses, Muslim student groups now shun one another on a confessional basis. Throughout the Arab and Persian media, moods of excommunication and denunciation are vocally expressed. Almost every day in Iraq, as has been well-reported, a mosque is blown up or a religious procession shredded by other Muslims. As is less well-reported, the same thing happens in Pakistan almost every week. And it is waiting to happen in other countries, too, as the Alawite sect that runs Syria (Alawism being a splinter of Shiism) gets ready for another confrontation with the Sunni Muslim Brotherhood, and as Sunni minorities in Iran become restive at the increasingly sectarian character of the Shiite dictatorship.”
