Maybe. There are 1 billion muslims in the world. The biggest estimate for al quada I've seen is 10,000. So, figuring that that is one of several muslim oriented terror networks, lets say that there are 100,000 muslim terrorists in the world. I think that's high, but whatever. This would meant that 0.01 percent of all muslims were terrorists
As for priests, the most recent number I found was 45,000 catholic priests nationaly. I have no idea how accurate that is, but we'll fly with it. Now, that means that if there are fewer pedophile priests than terrorist muslims, there will only be 4.5 bad priests in the united states.
So maybe there's a greater percentage of terrorist muslims, but I doubt it.
