Messianic zeal against schools

I've heard of this guy before, but this week City Pages did a full write up on his antics. The jist is that Paul Dorr, an extremely fundamentalist Christian who wants to destroy public schools and return to sectarian schools segregated by race, religion, and just about anything else, is injecting himself into school bond referenda all over the Midwest. He leaves sharply divided communities in his wake, but this is of no consequence to him.

Where do these people come from? Like most rabid fundies, he rants about homosexuality, and even claimed once that Budweiser promoted bestiality. I grew up in a pretty rural area, but I still don't know how these people are formed. When they keep to themselves, it's no big deal; live and let live and all that. But when it comes to this...well, it's pretty scary.
