I could go on and on, listing lots of things that I think are foolish and reprehensible, and declaring that those who hold those views are not True Christians. Unfortunately, I think that it all means that there aren't any Christians anywhere, and they're all damned dirty Christianists. I can't tell them apart from the Christians!
I'm afraid the Hutarees were Christian, real-live testifyin' preachifyin' Jebus-lovin' Bible-readin' Christians. They weren't Andrew Sullivan's preferred version of Christian, but then, a weird gay Catholic has about as much authority to define who gets to be Christian as an obnoxious and flamingly anti-religious atheist.
Well I defer to PZ on the spectrum of weirdness, but he ignores my central distinction between Christianity and Christianism.
Christianity flees power as Jesus did; Christianism seeks it above everything else. And there is nothing more powerful than killing others, except for torturing them. Hence my distinction, which I make from no authority. I merely think that declaring a homeless, apolitical, non-violent hippie in first century Palestine as someone who would bless a twenty-first century terrorist militia in North America is a bit of a stretch.
