I don't usually get involved in the gay marriage debate, since my passion really lies in the realm of food and the social ramifications related thereto. Recently, however, I ran across an article reposted on LAF (Ladies Against Feminism) - a fantastic site well worth exploring if you're not familiar with it - from The American Conservative about divorce and how it has shaped the gay marriage debate, often to the detriment of traditional marriage supporters.
Although I don't agree with everything it says, the article brings up some ideas and connections I hadn't thought about before with widespread ramifications. It's one of those articles that sticks with you, to be chewed on and digested slowly. If this is a subject you're passionate about, or you're interested in broadening your horizons a bit, you can find it here.
