It Can Have a Powerful Influence on the Weak Minded
Religion is one of my favorite subjects (duh), and I've read quite a few books on the subject and engaged in many discussions on the topic. He-Who-Shall-Not-Be-Named-Except-In-The-Case-Of-A-Subpeona is apparently reading up on religious terrorists and their motives.

However, Ms. Stern (the author) could've saved a lot of time by reading The Battle for God, which documents how fundamentalism foments, and how it has been around for ages. In becoming fundamentalist, you view yourself as being under attack, pushed to the edge by society, and you have no recourse but to fight back (against the evil heathens), as it is "God's will". Most of the time, this is brought about by secularists pushing to move forward too quickly for religion to keep up, which (time and again) creates a fundamentalist backlash. Of course, this is in no way a justification of tying explosives to yourself and blowing up a restaurant , unless you happen to be a dumb-fuck religious bitch (won't be seeing any of her again, at least).

Additionally, but not light reading, anyone interested in reading about how man created his gods, go get A History of God.
