How can so-called self-proclaimed "conservatives" object to two people committing to one another, and signing on the dotted line of that commitment?

What's the matter? Does it take away another of your pre-conceived ideas (or strawmen) about the sexual behavior of gays that they're promiscuous?

Also, I've never quite figured out what two people who are unlikely to ever want a relationship with a person of the opposite sex has to do with the sorry state of heterosexual marriages. There's your promiscuity!
