Rauch on Polygamy:

Jonathan Rauch gives what I think is the strongest case for being pro-gay marriage, but against polygamy. Now, this isn't to say that government shouldn't recognize polygamous marriages. Perhaps competing interests, like the freedom of adults to enter into whatever consensual contractual arrangements they wish, should trump the concerns that Rauch raises. (See my past post on the issue.)

However, Rauch's argument does put to rest the claim advanced by Stanley Kurtz et al. that "if we recognize gay marriage, we have no logical grounds for saying no to polygamy." Wrong, legalized polygamy raises a whole set of concerns not implicated by gay marriage.
