"Instead of fighting gay marriage, I’d like to help build new coalitions bringing together gays who want to strengthen marriage..."

"with straight people who want to do the same,"  says David Blankenhorn (formerly a conspicuous opponent of gay marriage).

For example, once we accept gay marriage, might we also agree that marrying before having children is a vital cultural value that all of us should do more to embrace? Can we agree that, for all lovers who want their love to last, marriage is preferable to cohabitation? Can we discuss whether both gays and straight people should think twice before denying children born through artificial reproductive technology the right to know and be known by their biological parents?

I don't know what that last question has to do with the rest of it. Putting that aside, he's talking about generic conservative values relating to marriage. I suppose it's easy to "agree" that these things are better than the alternative. It's harder to give up all that sex outside of marriage.

And let's not forget that one of the leading gay-rights voices, Dan Savage, has used his position to push adultery acceptance. 

[Savage] does not believe in promiscuity; indeed, his attacks on the anonymous-sex, gay-bathhouse culture were once taken as proof of a secret conservative agenda. And he does not believe that monogamy is wrong for all couples or even for most couples. Rather, he says that a more realistic sexual ethic would prize honesty, a little flexibility and, when necessary, forgiveness over absolute monogamy. And he believes nostalgically, like any good conservative, that we might look to the past for some clues.

“The mistake that straight people made,” Savage told me, “was imposing the monogamous expectation on men. Men were never expected to be monogamous. Men had concubines, mistresses and access to prostitutes, until everybody decided marriage had to be egalitar­ian and fairsey.” In the feminist revolution, rather than extending to women “the same latitude and license and pressure-release valve that men had always enjoyed,” we extended to men the confines women had always endured. “And it’s been a disaster for marriage.”

See? Straight people make the "mistake" of not structuring sexual norms around the male. That's the message from one man who's only interested in sex with men. What about women? Well, let them "enjoy" the sexuality that man take to naturally. Liberation, baby. The man who has no desire whatsoever to have sex with bodies like yours says so.

I can't imagine that people like Savage will tone it down because Blankenhorn is now offering to form a coalition. Wouldn't he — as I do — write off Blankenhorn as a guy who's trying to re-leverage his importance? Who needs him?
