Well I saw this new category and I feel the need to testify!
I was born an atheist and will happily die as one.
Extended family and peers tried to pressure me into being a christian my parents took a more neutral position and encouraged me to think for myself and make up my own mind.
By 8 I had serious questions as to the validity of religious claim and by 10 I declared myself free of delusion as an atheist. Living in rural Alberta Canada I was often pick on and excluded for my lack of belief, however, this came to an abrupt end when I turn 15 as I grew and was farm kid strong and athletic, and tired of being pick on. Didn't stop all of the exclusion but, picking on my just wasn't going to happen.
I have testified!
