Why do some people walk away from the Christian Faith?

I have read profile again and again of jellies that grew up christian and left the faith. Those are the ones that I would like an answer from. The specific question is what was the breaking point?

I expect this to bring a lot of commentary on inconsistencies in the bible or behavior of christains. That may be your answer and if so, ok, but are there other reasons.

All readers, please refrain from debating. This question seeks to listen to this specific group with regard to this specific question. I plan on not writing another word in this thread so, now I turn the floor over.
