In the beginning of Christianity? I'm afraid history disagrees as the founders of that religion most probably had a legitimate belief in their organization. As is a prime example in the amount of splinter factions of Christianity and Islam, the real lunatics came out when the issue of interpretation reared its head.
I was spinning off something space captain had said. Just counterpoint rhetoric.
As for religion in general...whatever helps someone sleep at night. If it becomes intrusive, I'll be happy to send them to meet the deity of their choice.
