No offense meant, but...do you have a source for that? If I am wrong about him, well, no problem. LOL After all, I can hardly be glad if he was a Christian, kwim?
From what I have found in just the past few minutes, he seems to have been affiliated with something called Christian Identity movement...apparently a bunch of racist militia types who quoted Scripture to justify violence against both the government and minorities such as the Jews. I have only seen one article, by contrast, that states he wasn't a Christian. The rest seem to imply it. The result, to me, is that I am now uncertain that he was a Christian, but I cannot be convinced as yet that he wasn't one, at least marginally.
