Yes, John500AF, we have members who were extremely religious prior to becoming atheists and seeking out our group. Some were raised their entire childhoods and spent their early adulthoods as strict adherents to churches and religious sects. They were taught apostasy was evil, then through thoughtful analysis realized what they had been taught was entirely unsubstantiated and counter to the truth. It is pretty common, actually. We have members who are former Christians, Mormons, Jehovah's Witnesses, etc.
