We are now in the twenty-first century. Perhaps we should have better reasons for depriving our neighbors of their liberty at gunpoint. Given the magnitude of the real problems that confront us—terrorism, nuclear proliferation, the spread of infectious disease, failing infrastructure, lack of adequate funds for education and health care, etc.—our war on sin is so outrageously unwise as to almost defy rational comment. How have we grown so blind to our deeper interests? And how have we managed to enact such policies with so little substantive debate?
