The facts don't support your opinion of 10-15 thousand Muslims actively or other wise supporting terrism for any reason.
As for the "side not:" I personally know one Muslim, he owns the auto repair shop I go to. Nice guy, honest and fair to the best of my knowledge.
We should and do, monitor Muslim groups for terrorist links/ funding and subversion because the Masques and overseas trips to Terror U. are where they are being recuited from. So that is where we should look.
I'd say it's safe to say there are around 300 million Muslims who are active in jihad in one form or another.
