Most of the evil that people assosiate with muslims is much more cultural based than religion. Illiteracy in arabic countries is just enourmous. Combine the illiteracy with being stupid, and a culture of believing in authority. All you have to do is a very wicked or extremely corrupt religious leader that uses those poor stupid souls to be of some use by external spy agencies.
Illiteracy and believe in authority is the key problem here. And yes "we" in the western world have stupid and illiterate people, but lucky for us potential enemies have very weak agencies of influens, nothing compared to KGB, CIA, MOSAD etc.
. Abaolutely, retaliation and criminal groups rise from the poor and devastated areas, juat like middle east and Africa, it a mess there, since US was messing with the governmenta that werent suiting thw politics of Washington.
. Illiteracy and the simple mindedness that comes with lack of education is the ground where manipulation can do it's best, coubries like that with it's extrwmist governments are the problem and religion, in this case islam, is just a a catalyst.
