The real question is: why do people succumb to the god delusion? why would you believe with all your heart in something that the only reason you believe it is because thats what your parents believed? (You in general, not person-specific.) What makes people so sure about the factual accuracy of a book with no evidence for its accuracy, yet there is skeptism among these same people about quantifiable, substantiated science. Its called fear. As I believe fear will exist well into this century, so to may religion.
Hey, back, off, buddy, that's my post!

This is close to what I would have posted had it been later in the day. As it is, it's morning, and I'm not a morning person.
It really is amazing that once one removes the 'god exists' goggles and looks at the world, it becomes so obvious - the similarities in how religions run despite the differences in their worldviews, how totally ridiculous the whole concept of a sentient deity is in the face of the facts as we understand them, what a perfect tool for control religion is... the thought of faith quickly becomes laughable once one frees oneself of it.
I believe that in general, leaders don't believe this crap. It's just a tool to them. I don't think any of the popes have been true believers, nor any president before Dubyah. I do believe Dubyah was chosen because he is a believer, and therefore more easily manipulated by Daddy, Cheney, Ashcroft, and their ilk.
I believe religion may be with us for the long haul, but also believe that the world would be best served by its demise. It is an antiquated concept responsible for the vast majority of the more morally reprehensible activities of the human race - a tool of subjugation and control so horrible it defies description.
