Here's an example of "born again" being used in a political context - and there are plenty more. Born again Socialist, born again Feminist - and of course born again Atheist (I see there's even a book with that title, by an atheist happy to adopt it!) I don't think this excellent metaphor should be abandoned to weird American fundamentalists, and clearly so do a lot of other people who wouldn't have too much in common.

"Why should the devil have all the best tunes?" Even if the devil's voice is coming from someone like that unspeakable "Kevin Swanson", masquerading as a Man of God.
