The worrisome part of that profile, and of the whole evangelical Christian political movement in the US in general, is how a pretty substantial chunk of the country is dropping out of social institutions and building its own parallel ones. Religious colleges, the home school movement, books and documentaries that get treated like samizdat, novels, music, etc.
I'm always optimistic that America will pull through, or at least muddle along, despite all the anger and discord and crap in our politics, because at the end of the day everyone has to live with each other. I don't think hardcore Christians are going to go to the lengths that Scientologists or fringe Mormons do, but millions of people deliberately alienating themselves from the rest of the country is an unsettling idea.
