An argument I think advocates of marriage equality should stress (2)

As I noted earlier,

we should decide the scope of secular marriage under secular principles rather than any particular church's interpretation of Scripture. This argument must be a strong one, since whenever I bring it up, the 'phobes immediately change the subject.

Now, it appears that the Second Circuit agrees with me. From the opinion:

But law (federal or state) is not concerned with holy matrimony. Government deals with marriage as a civil status--however fundamental--and New York has elected to extend that status to same-sex couples. A state may enforce and dissolve a couple’s marriage, but it cannot sanctify or bless it. For that, the pair must go next door.
