I feel like it's a key piece of US political machinery, as probably the single biggest cultural engine for churning out the single-issue voters needed to scare the left into teaming up with Liberal ghouls.

I also think it's something that can be tough to explain to people who've never been enmeshed in it. I know I see a lot of people who grew up with religion as an unobtrusive, cultural backdrop wildly misunderstand Evangelical fervor.
