Asperger's Poster Child
Actually I can give you proven test for God, People that hate God that get saved they change everything they once love they now hate and Every thing they hated they now love. I met a guy a few months ago that was a staunch atheist. He went to see his professor not knowing he was a Christian and the guy had a poster on his door about the 3 literal days of creation.
I've encountered a few people who went in the opposite direction - they were staunch fundamentalists and then became staunch atheists, but still retaining a zeal that was overwhelming. I find myself repulsed by both camps' insistence on their absolute certanity. I have never encountered an atheist who had formerly worshipped in a moderate denomination, or a moderate worshipper who was a former atheist, although such people may exist.
The likely explanation is that some people have fanatical personalities and are attracted to extreme ideological positions because they are looking for external meaning. Two commentators, David Horowitz and John Stossel, went from being smugly self-righteous far-lefties to being smugly self-righteous far-righties, without changing their basic personalities.
