CO brought up an awesome point -- we've never discussed just how many of the 1.4 billion Muslims are extremists/terrorists. I'd like to do some research before I add my two cents but I will throw out a ballpark guess. I don't think there are more than 100,000 Muslim extremist terrorists in the entire world. Edit: I was looking around a bit to get a better estimate of how many Muslims may be considered Muslim and I came up with different guess of about 40% of Muslims being "fundamental" with around 5,000,000-10,000,000 being considered terrorists/supporting cast. I stand by 100,000 or so being the actual terrorists to carry out the acts.
