Yeah, well this skeptic didn't come to this position without a great deal of thought about it.
I would bet that there are a pile more former Christians who've come to a similar conclusion as I did after examining their faith.
IME, you are absolutely correct. I was a "born again believer" for 20 years. During my transition, most atheist and agnostic I encountered were once believers. One acquaintance actually felt the calling to become a minister and the more in depth he studied, the more skeptical he became.
