Ezra gets it

The Christian Right is a throwback to the pre-Enlightenment era.

For the casually spiritual, the secular, the agnostic, it simply doesn't make sense that you'd legislate in accordance with an outdated book rather than cutting edge social science. But for those who truly believe, homosexuality isn't just unpleasant, but a stain on our world. Immorality is an affront to God. It doesn't matter what social science says or public policy students discover, you legislate based on morality, not results."
