There were about 3,000 peace-loving people drinking coffee and working at their desks on 9/11/1. I would bet that most of them were quite a bit like us. I'm sure many were religious, probably most in that live-and-let-live moderately religious way that characterizes most of your country and mine. They probably believed that most people do have a right to their own opinion, and that God has "many doorways through which the faithful may enter". What killed them was a catastrophe engineered by a group of men who didn't see the world in that way at all.

These hijackers didn't act to make a political statement. They didn't go to their deaths shouting "long live Osama" or "God Bless Syria". They were possessed by religious fervor.
This is where I disagree about the Almighty Dollar. Say what you will, the Almighty Dollar won't coerce someone into driving a plane into a building, or beheading an Irish relief worker. Because there is SOME LOGIC to what someone will do for money, there are predictable outcomes. A person acting on the tenets of an irrational belief system is almost completely unpredictable. He will carry you, or me, or the people drinking coffee in Trade Center 1, kicking and screaming into his World View.
Much of the Bible and the Koran are primitive texts that refer to strife and scuffling among people thousands of years ago, when a man could pick up a sword and cleanse the world of his enemies in the name of God. And there are plenty of specific references to doing just that in both of them. Well, nowadays, a man doesn't need anything as crude as a sword. A vest loaded with C4, or a truck, or an airliner, or a freighter can multiply his righteous power one million fold.

And the fact, unpleasant as it is, is that these methods of dealing with unbelievers are as much a part of sacred text as are admonitions to "love thy neighbor" or "turn the other cheek". Those moderate Muslims and moderate Christians who want to live and let live have simply decided, as they have decided to not take the 6 day creation story literally, to ignore these passages, while tolerating those who follow the literal truth.

If we tolerate their beliefs, do we not enable their actions?
