For whatever religion you are, why? What brought you to that religion?
I am of the atheist-agnostic type, I do not believe in god at all, but I don't(usually) claim there is no god.
I was bought up in a Christian household, so most I know about religion is from a Christians standpoint. So all my religious qualms(I don't if this is the right word but) are toward Christianity. Personally I don't think that people are part of whatever religious group because of genuine belief, but because their parents were Christians/Muslim/etc. Of course this is not true for all cases but that is my general thoughts on the matter.
