Religion as a psychological tool is a very sad thing. But it's a very common thought, one I grew up with. In fact, I only started praying while still thinking it was all fake, but needing some kind of mental help past my problem in life at the time. So I understand that theory as well as anyone here.

But not all religions are created equal. The Protestant religions are emasculated to some degree. Since they're based around rejecting the truth, their foundation is all wrong, and they can never get back to reality. Unfortunately, they turn many people away from Christianity.

But that's not necessarily true. Those who keep looking for it will find it in Catholicism, just like John Henry Newman did. As he said, "to be deep in history is to cease to be Protestant." But more often, people don't really want to find out the truth. So they reject religion altogether. Except as a psychological tool.
