Taught to be nutty? I try to look at it more kindly, as they are taught to accept on faith certain things, and as they get older, they either stop questioning, or perhaps stop noticing contradicitons between Church teachings and scientific ones. Or perhaps, as some do, look for quasi-scientific explanations for justification of their faith.
And look, it's not just the Fundies, either. THe other day, our babysitter's mother mentioned to my wife that she just found out last week that the story of Adam & Eve and the Garden was just that: a story. She had always beleived in the literal explanation, so much so that she never bothered to try to reconcile in her mind anything she'd heard about evolution, Big Bang, etc. This woman is 45 years old, has a responsible job, and has raised several kids - nice kids, too. Devout Catholic. And until last week, still believing in Adam & Eve. She's devastated, BTW, so much so that she made an appt with her priest to sit down and talk about this.
My point is that even though I've discovered this, I still dont' consider her to be "nutty" or have "outlandish" views. Her kids will still watch my daughter, we'll still exchange Xmas cards.
