And since imposing criminal sanctions based on religious values in this (and other) regard has been constitutional since the beginning, that's all the reason I need. If a majority of the people support a criminal law based purely on ethical reasons with a religious foundation then that is their right in a democratic republic, baby. Who are you to say your cost/benifit empirical analysis is somehow a more authoritative or moral basis for criminal law than a motivation based on divine revelation from God? If you can bring enough people to your way of thinking so they vote in different laws, go for it. But so far your position has consistently been rejected over a thousand years over a broad spectrum of cultures. And I will continue to support laws consistent with my theistic presuppositions.
Really?
