What do you mean remain? You always talk about religion as some sort of inevitability. Why wouldn't I remain? If I hadn't read any books and I hadn't gotten more interested in religion, then I would have just lived my life being an atheist. It's not like I have people coming to my house or kidnap me on the street to convert me to their religion.
At this point after all that we've been through I can only take it that you are deliberately trying to troll me by saying "no rational basis". I've given you my rational basis in spades.
But to answer your question, it went something like this (all ages approximate):
Age 1: Baptized.
Age 2: First time in church after I had developed speech and understanding of language.
Age 4: First conversations about religion with parents.
Age 7-8: Reading illustrated bible for kids.
Age 8: First Communion.
Age 8-14: "Sunday school" one afternoon after school per week with a priest. Very liberal content, mentions of historical rituals and heavy focus on the "mystical" aspects of theology. I quite liked these. Once played football on church premises with the priest.
Age 14: Confirmation.
Age 15: First serious reflections on the question of theology and god. Decided I could not remember ever actually believing god. At best I "could not be sure". Decided to stop going to church since the basis of that whole activity is faith. Other than the faith part, I had nothing against the church, except Mass always bored me. Official status: agnostic.
Age 21+: Started getting interested in religion again, but from a different perspective. "Discovered" atheism as an intellectual movement, not merely someone telling me they did not believe in god.
Age 25: Redefined agnostic to atheist, for all practical purposes. "Soft atheism" some people call this. Influence: Richard Dawkins, Sam Harris.
Age 27: Given a reference to George Smith's book by aca, where I found a complete argument for atheism and a refutation of agnosticism. Redefined as "strict atheist".
So I was a late starter, a lot of kids I knew had decided this issue for themselves years before I had. But as with many people brought up in a religious tradition, I just went along with it because it seemed the "normal" thing to do.
Nope, but it's hardly unusual for people on opposite sides to suspect each other of ulterior motives. Frankly I would be more willing to admit that emotion comes into it, but that ultimately defeats my purpose, because I know your debating style is such as to jump on flaws and blow them out of proportion. If I saw that yes I do feel a certain emotional pull in this matter, although it is in no way the main thrust, you will turn around and claim that I'm being completely irrational and overcome by emotion, right?
I wish you wouldn't resort to such guerrilla tactics.
