Often, I hear certain people who used to have religious views (mainly Christian) refer to themselves as an ex-believer. Forgive me, but I find this concept hard to define. It would be as if I once went to visit my Uncle Bill in New York City when I was 7. After meeting him and getting to know his farm, I came home with my parents. Years later, my parents told me that Uncle Bill was not our real Uncle. Who did I meet, then?
Don't give me the suggestibility psychological arguments. I maintain that those who used to believe in God never actually experienced meeting Him. If they had, they would know it!
