Terry Pratchett works, though. I can't really see a kid ever getting religion after that.

I would agree in principle -- Pratchett's work is a remarkably good illustration of what the world would look like if supernaturalist thinking made a scrap of sense -- except that the most enthusiastic Pratchett fan I ever met was (unfortunately for me) also a devout theist.

I think I have ceased to be surprised at the ability of intelligent people to compartmentalize.
