Well, all I can really say is that my mum was sent to a french catholic school, and that didn't last long
. Then half of her family is either czech ex-communists, but who are still atheist, and the other is catholic. My father came from a mixed family of agnostics and irish protestants.
They are both agnostic now, and have been nice enough to let me decide my personal values when it comes to such matters.
Personally though, I've tried since a young age a few religions and philosophies here and there, and have pretty much settled upon atheistic/ignostic existentialism.
