I'm all in favour of not jerking off over our ability to outthink Christian fundamentalists (also: some Christian fundamentalists are actually pretty damn smart in their domains of expertise), but it doesn't look to me as if that's what Benquo's doing. I think he's saying: OK, this guy managed to escape fundamentalism, which we know to be difficult even for smart people, so can we see what enabled him to do it and try to learn from that?.
I do agree with Viliam that this should have been a comment in the Open Thread, though.
This person seems to have the virtue of non-compartmentalization. What rationalist skill can we learn from this? Maybe look for ways a strong belief in one domain, to another where it's more testable?
