Most of my forays into spiritualism, natural history, biblical criticism, and biology have started out as ways of poking holes in Christian fundamentalists. Oh, they lead me to other, far greater things, but that's where they started out. Unfortunately by the time I'd got really well armed I'd moved completely out of fundieland (Arkansas), and never got to play smackdown with any of them.
But these guys did, and it was glorious. I'd've paid money to see that, I sure would!
