I love the potential which comes from people with very different worldviews getting together to share their beliefs because, at best, it might turn out like this. Easily my favourite novel, and filled to the core with weird or just plain crazy people arguing about religion. Call me low brow, but I have to maintain that I've received more enjoyment out of that little dime-store sci-fi novel than from any of the renowned greats in literature. It's hard not to love when people reach into the core of their beliefs, pull out shining models of how their minds work, and present it for examination.
I loath discussions of religion, because in the vast majority of cases they end up more like this. Except with some examples of the answer being flipped to the opposite side of the coin. Well, that and more exclamation marks, and words spelled out in caps, and the inevitable mention of Hitler somewhere.
Somehow though, even the latter tend to have nuggets of pure gold scattered throughout.
