Bart has never held back from opposing Christian fundamentalism (and every other religious fundamentalism), even though he was once a fundamentalist himself. And many fundamentalists consider (and call) him the spawn of the Devil for his attempts to expose the flaws of fundamentalist thinking, in part because he understands the view from the inside. But Bart has never publicly talked about how being a fundamentalist had a serious upside and played a positive role in his life, affecting everything that came after in some extraordinarily helpful ways.

In this episode he spills the beans on how being a fundamentalist proved, in some ways, to be a good thing. (Even if he doesn't advise going there!)
