I was brought up a Christian, and went to church most Sunday's until I was old enough to make my own decision not to go. I'm not entirely sure why I have these beliefs, but they are there. I'd call myself an agnostic also, searching for some answers.
well it matters a lot if we are acting socially, morally and politically based on fairly tales. especially when they are competing fairy tales and people are willing to risk it all to defend them.
I don't think somebody using karma as a way to better their life and act morally in decision making is a problem at all. Not everything has to be calculated with precision, a bit of faith in a decision isn't a bad thing until radicalism is brought into the equation.
