I've always wondered if religious fanaticism could be grounds to show mental instability. Like if I went to a judge and said "My wife believes that her, her family, and christians friends are all going to be raptured. They believe that one day they will magically disappear, leaving behind a pile of neatly folded clothes. Then once they're gone, some satanic demigod will come and destroy the earth". Would a judge, assuming they were not christian, accept that as grounds that she is unbalanced? or would she be protected because it's religion?
