I live in Indiana, and have all my life, in a town no bigger than a postage stamp, but somehow has four churches. I have never attended church, and I have not read the Bible as a whole, despite efforts over the years. I was raised by a pair of people that didn't fit in with other people in the community, let alone belong together.
My mother is a self-proclaimed Christian. I still don't know what my father is, but I figure he is probably Atheist, Agnostic, maybe he is his own brand of hateful and nothing else. I wasn't taught religion because my mother was too frightened of my father, and I wasn't taught Atheism, because my father never thought I was smart enough to understand.
I remember as a small, thoughtful child, none of the religious concepts stuck. When my mother brought them up, it was more like a game of make-believe to me. As though she were saying 'We're going to pretend we're in the land of Oz, today. Then tomorrow God will make a rainbow and angels will guard you while you sleep and the Devil will stay far away.' This was only on a very fleeting occasion.
I played along for years until I just couldn't anymore. I explored Paganism and Wicca. I kept them a secret, which at 13 as an only child is incredibly easy, unless you are me. Of course I got caught and all Hell broke loose (pardon the pun). My parents were furious. Mom because she was left standing confused going 'But that stuff is make believe... I don't understand how you could even begin to consider that rubbish as real.' And my father was going ' Uhg, no. This is just as dumb as what your mother believes in. Just stop, stop it all.' So I got a lot of mixes signals. My friends had similar experiences, looking for their own answers. The problem was they felt make believe, too. Eventually I just said 'Why can't I just be honest and say I think all this is crap?' So that is what I did.
