There are different Muslim sects

William Dalrymple writes at the New York Times about the mis-named 'Ground Zero Mosque.'

Feisal Abdul Rauf of the Cordoba Initiative is one of America’s leading thinkers of Sufism, the mystical form of Islam, which in terms of goals and outlook couldn’t be farther from the violent Wahhabism of the jihadists. His videos and sermons preach love, the remembrance of God (or “zikr”) and reconciliation. His slightly New Agey rhetoric makes him sound, for better or worse, like a Muslim Deepak Chopra. But in the eyes of Osama bin Laden and the Taliban, he is an infidel-loving, grave-worshiping apostate; they no doubt regard him as a legitimate target for assassination.
