This is a conversation about what is, not what should be. And right now, homosexual marriages in Massachusetts, Vermont, Hawaii or anywhere else are legally recognized in all 50 states. Therefore, the federalism canard in defense of homosexual marriage (which was the crux of the post I was responding to) is entirely bogus and thoroughly dishonest.
Oh, dishonest, well, excuse me. Then by all means, carry on your discussion which is based on unConstitutional laws. Keep the unConstitutional train rolling. In fact, you should argue every left wing proposition based on their definition of the facts. That seems to have worked out so well in the past.
BTW, this is the strategy that gave us a federal abortion law. Good luck!
