Is same-sex marriage a good idea? Or is an intact biological family the best environment for raising a child? The answer may turn out to be yes and yes.

That’s the curious implication of a study reported yesterday in Social Science Research andoutlined in Slate today by its principal investigator, sociologist Mark Regnerus. The study, which found inferior economic, educational, social, and psychological outcomes among children of gay parents, comes across as evidence that homosexuals are unfit to raise kids. But the study doesn’t document the failure of same-sex marriage. It documents the failure of the closeted, broken, and unstable households that preceded same-sex marriage.
