It would be nice if once, just once, these groups representing 'mainstream' Muslims would publicly and loudly denounce the radical fundamentalist elements in their religion and take steps to isolate them.
Perhaps they know that if they did, they might get killed, in the name of Islam of course.
I saw a post on FR just today where a Muslim leader said that there are two brands of Islam; one which embraces violence as means to an end and pursues a mindless fundamentalism. The other is more peaceful. These forms of Islam are at war around the world.
Isn't that sufficient condemnation?
