Honestly, I was expecting it to go the other way.
Patt Morrison had a lawyer for the losing side on her show a few minutes ago, and he basically framed his position this way: Allowing same-sex couples to get married places personal choice above community standards. Allowing people to ignore community standards will erode the morality of our culture. That sounds like a pretty weird argument for a supposedly conservative point of view.
When it comes to something as private and personal as marriage, let community standards be damned. America's uniqueness flows from its protection of personal liberty, even when that means protecting things that you would not do yourself, or that make you feel uncomfortable when other people do them. I've visited the Harmonious Society, and I like it here better. A lot of blood has been spilled over the years for the liberty we now enjoy. If living in a free society means we have to watch dudes kissing on TV, I'd say that's a bargain price for a lot of protected liberty.
