"One should always speak good of the dead. Joan is dead. Good."
If you were raised in a moderately conservative church, there's a good chance that you encountered some variation of the Preacher's Kid. On the face, they're perfect Christian sons and daughters, in the pew with straight back and perfect grooming and butter wouldn't melt in their mouth -- it's all "yes, ma'am," and "no, sir," and "what would Jesus do?"
But once the adults are out of sight, they're grabbing the bottle and giving out a big fat wink before they take a long, hard pull and beckon for a hit off the joint. Then it's off to deflower a virgin or get nasty with that smoker-boy in the leather jacket.
Any convention-city prostitute can tell you that the Republicans are the kinky ones, and they can also tell you why: It's the repression. They want to both please and resist mommy and daddy at the same time. They want to be both bad and good. They're the Preacher's Kid writ on grand scale.
