Hey. You have to question their loyalties.

I have yet to hear them condemn any of the murderous activities around the world.

Not asking for much. How about:

"We, the Muslim leadership, think that what the extremists are doing is absolutely evil and is in no way excused by the Muslim community. And we will do everything possible can to help catch these evil people."

Yup. That should about do it.

I await the anticipated flurry of " you can't believe them" posts, but if that's the case why bother asking in the first place ?
