I don't know if you were suggesting it, but I don't think this fits into the "right wing" category any more than Earth Liberation Front fits into "left wing". While they were targeting law enforcement (which, I guess could be considered "anti-government" and thus closer to the "limited gov't" right wing), the motivation seemed to be not political, but rather some kook supernatural belief that, unfortunately, they think is justified in scripture.

Earlier today I had the pleasure of hearing people talk about this incident as though this is mainstream Christianity (or even substantially similar to Christianity). It's moments like these when I can better relate to Muslims who get annoyed when their religion gets a bad name from terrorists. Start with an ideology, go find a religious text, skim through it to find selected passages taken out of context that you can twist to fit your ends and then, presto, you're now a representative of that religion. Awesome.
