A rather brilliant analysis of why he feels about gays the way he does:
This is why we cannot argue with people who subscribe to this framework: there is simply too much at stake for them. They have wedded their fundamental sense of okay-ness to the truthfulness of a set of doctrines. Not only is sociology not at issue for Rick Santorum, Romans isn’t either. What is at stake is his very sense that the world is a good place, that things are basically okay, and that he himself is okay as a result. That may be expressed in a theological framework, but it is a psychological reality. If I marry my partner, therefore, Rick Santorum is not okay. The rest is window dressing.
