Copy this sentence into your LiveJournal if you're in a heterosexual marriage, and you don't want it "protected" by the bigots who think that gay marriage hurts it somehow.
It misses the point. Now, I don't happen to agree with the point, but it irks me that people on my side of the fence don't bother to know their enemies. The point is it hurts the institution of marriage. It doesn't harm any individual marriages. I thought about going into gory detail on why, but I frankly don't like these people enough to defend them that thoroughly.
