I rarely ever get the chance to converse with other atheists, and this place seems like the place to be if that's what you want to do.
The religion you left
Why you left your religion.
My parents attempted to raise me in a Catholic environment by sending me to a Catholic school for kindergarten and first grade, and that fortunately failed. I don't think I ever really believed in a god, so I'm hesitant to say that I left Catholicism. When I prayed, I never really thought that somebody was listening; I just did it because that's what I was told to do. Indoctrination? Yeah.
