Well if you're going to toss out the Federalist argument for States Rights and de-centralized governance, then we need to have a discussion of what "new" civil rights we're talking about here. I'm no legal expert, so I can't speak one way or the other on the issue of whether or not Power of Attourney extends across State lines.
And I'm not so sure the government should get into the process of defining and validating the "rights" of couples, or groups. It seems to me the Rights to which we are all afforded are Individual rights. It's a slippery slope if we get in the business of defining rights for anything but individual persons. We'll have to start defining every conceivable couples-rights out there: Hetersexual, Homosexual, Bisexual, Polygamist, etc...
And I don't see Marriage as a "right', per-say.
It's essentially the evolution of a Religious Sacrament that has been adopted by Government as contractual priveledge. It is specifically and exclusively extended to a heterosexual couples based on thousands of years of sociological, historical, cultural, and biological proof that such an arrangement, at large, is beneficial to the advancement of civilization due to the unique capabilities of a heterosexual couple to reproduce and provide a stable environment for the raising of children.
