Why do you become atheist just because one religious control group got the best of you? Is it because you feel used? Or abused? or just plain stupid? Please enlighten me on this point.
Ok, since you asked.
The answer is, of course, that it is not because of one religious group, although it started there. Once you start to question, really question, what you have been told to believe (for example, God exists, the afterlife and the hope of the Resurrection are all things that are true, and the Good News of the Kingdom, etc.) you begin to see the cracks in the entire ediface. Not used and abused, although those feelings factored into it, and stupid, well, not that either. Just the opposite, from my perspective. It takes a lot of learning to see things clearly, separating fact from fantasy, evidence from faith. Some arrive here sooner than others. For me it took more than five decades of searching to find real truth.
