I Thought This Horse Was Dead Already!

Driving home today I heard in defense of gay "marriage" the old standby, "You can't legislate morality!" PUHLEEZE! Any law is the legislation of some morality. Even anarchy, a state of lawlessness, is the "legislation" of someone's "morality." So, someone please cite for us a legislated "un-morality." But you're more likely to see a square circle, marvel at government efficiency, or sip on some hot iced tea.
