Remember that post I wrote a couple weeks ago on gay marriage?
How about this particular unintended consequence?
Dallas Judge's Ruling Saying Gay Couple could Divorce in Texas Rejected on Appeal.
Basically, two guys got married in Massachusetts, where it's legal. They then moved to Texas (for reasons I can't fathom), where it's not. Now they can't get a divorce.
I can imagine no clearer illustration to explain why this issue should most certainly not be left to the states to decide. I mean, other than the fact that "states rights" have been a cover argument for, "We walk to be a bunch of bigoted fuckwits and don't want anyone telling us not to be," since some time in the neighborhood of John C. Calhoun.
