I read The God Delusion by Richard Dawkins back when it first came out. Before that time, I didn't believe in Yahweh, but had a vague new age spirituality, strongly influenced by Richard Bach and the like. I was immortal, and could bend the laws of physics if i really needed to.
After finishing The God Delusion, I was forced to choose between immortality and intellectual integrity. It was a painful choice, but I chose the latter and never looked back.
It turns out I disbelieve in almost all the same gods as most theists
I have a few things to say about the Contradictions in allegedly inerrant books.
