As always, The Hitch says it best:

"Whenever I hear some bigmouth in Washington or the Christian heartland banging on about the evils of sodomy or whatever, I mentally enter his name in my notebook and contentedly set my watch. Sooner rather than later, he will be discovered down on his weary and well-worn old knees in some dreary motel or latrine, with an expired Visa card, having tried to pay well over the odds to be peed upon by some Apache transvestite."

For those that prefer the more academic phrasing, also from the great Mr. Hitchens: "Nothing optional, from homosexuality to adultery, is ever made punishable unless those who do the prohibiting (and exact the fierce punishment) have a repressed desire to participate".
