Make the case for gay marriage, not against social conservatives.
UPDATE from Bruce: Conservative Brawler has a related perspective on this topic.
When looking at the gay marriage issue, one has to ponder… what is this really all about? Gays can already have any relationship they wish, what they’re fighting for here is state-recognized status. Why? They can call themselves “married” until they’re blue in the face, why do they need to the state to recognize their union? Because with state-recognition comes state benefits. And here we find the crux of the issue for the intellectual conservative – the reason the intellectual conservative wants gay marriage to be decided state-by-state isn’t because he has some vehement hatred for gays, but because he believes that a state’s citizens should have the autonomy to decide what they will and will not subsidize.
