I suppose I ought to introduce myself. I'm relatively new to atheism. I've only been an atheist for about a year.
I was raised very Catholic; In fact my mom was almost a nun before she decided to get married. Well, I started to drift away from religion and the Catholic guilt kicked in. I decided to become super-Catholic and ignore all of the bad bits of the Bible and awful social rules the church has.
I eventually came to my senses and just couldn't ignore God's crimes anymore. I formally defected from the church, got excommunicated and put the letter from the bishop confirming my defection/excommunication in a frame on the wall... no closet for me.
It's lovely to see so many other non-theists here. :)
