A female friend of mine had a horrible experience. Her aunt snooped in her room and found atheist literature, told her parents, she admitted that she had become an atheist, and they kicked her out of the house and cut off her college money. It was several years before they would even speak to her again and a few more before she was trusted to be around her nieces and nephews unsupervised. Her parents are Pentecostal like mine, but I was in my 40s when I came out to my father's side of the family and already lived in a different state, so it probably helped that I wasn't as vulnerable as my friend.
I'm not anti-Christian. I'm anti-stupid.
