I think what you're missing is that a lot people in the Middle East are uneducated, especially in places like remote mountains of Iran/Afghanistan/Pakistan. Being a believer doesn't make you stupid, I never stated that nor can I see how you could come to that conclusion from me simply stating that the educated Muslim, for the most part, wouldn't be expected to believe in Sharia Law because they are educated.
Anywho, my broader point was that the "state" of the Middle East at the time when, say, al Qaeda and the Taliban were able to come into power, and flourish, was created by, not religion, but global powers and their greed. America, and their selective aid to different countries, (like Iran who were being annihilation by Iraq; during the time Russians had invaded Afghanistan. All the while "democratic" Monarchies were being raised around the region, which we backed) created the reason why a quaker won't strap a bomb to his/her back but a very poor young man from one of these countries would.
I'm just pointing out that the reasons why things are the way they "are" isn't because a few rich and educated leaders of the 'jihadist' movement, as people love to put it, in my opinion Western Powers created this situation. Tis all.
