Just thought of something else. For two years, I was a square peg in a small denominational college in Kentucky. Folk music was one of the things that kept me sane. It was just bawdy enough to counteract the Precious Moment spirituality so many of my friends practiced.
One night I found myself at a Christian coffee house. A friend and I stood the maudlin music as long as we could, then we went out to the foyer, and swapped dirty songs. "The Bastard King Of England" is not one of my favorites. But that night it was pleasantly refreshing.
When the tornadoes hit Kentucky that spring, my friend of the dirty songs took time off from class to join the relief efforts. Most of the alleged Christians didn't even donate a pair of socks.
