Raised United Pentecostal on my dad's side and Assembly of God on my mother's. Was probably 16 before I had real doubts (having just read the Bible through twice, once KJV, once Living Bible). It would be about 20 more years before I thought of myself as an atheist. Maybe because my process was slow enough to give me a 'soft landing', I didn't have a lot of issues with my religious upbringing by then. My parents did the best they knew how, like the vast majority of parents.
I'm not anti-Christian. I'm anti-stupid.
