Gertrude's Law

Hamlet's mother, Gertrude, is famous for her quote "The lady doth protest too much, methinks". Gertrude's Law states that if a person is overly passionate about condemning a certain lifestyle choice, they most likely engage in that lifestyle secretly. Some notable examples are Jimmy Swaggart, Ted Haggard, and most recently Arifinto, an Indonesian MP who helped pass an anti-pornography law. He was later photographed looking at porn on his iPad during a parliamentary debate.

Based on Shakespeare's "Hamlet", this is an adaptation of "The lady doth protest too much, methinks." It can be used for when anti-homosexual priests get caught having sex with male escorts or, more generally, when somebody fights against a proclivity that they, themselves, engage in.
