I'm very skeptical about man being biologically "hard wired" for religion, but really have no more case against the concept than my feeling that it's something of a stretch.

Certainly there is no end of examples of people who wouldn't touch traditional religion with a ten foot pole, but at the same time hold other beliefs with fervor indistinguishable from that of the deeply religious.

I've seen one example that strikes me as particularly odd, and a bit inane, among nudists. For the most part, I've found most of them to be folks who just find it pleasant to relax in the open air, or water, sans clothing. But there are a minority who are highly doctrinare; it's typical for them to lambast a "clothing optional" approach, insisting on consistent total nudity, much the same as fundamentalists won't acknowledge liberal believers as true Christians.
