Specifically, state governors.
As I've been going on about in someone else's thread (sorry, Jeff), individual people, even conservative Christians, are very chary of defying court decisions and/or ordinances or laws. It would help them a lot if some officials backed them up.
Suppose, which God forbid, that SCOTUS declares homosexual simulacra of marriage to be a constitutional right. Or suppose that more state supreme courts do so. What we desperately need are some governors who are willing to defend marriage within their states. Upholding their oath to the laws and constitution of their own state, and defying the ridiculous pretense of "interpretation" that says that the U.S. or state constitution requires homosexual "marriage," such governors should issue an executive order that no marriage licenses be given to anyone other than one man and one woman.
Preferably there would be several such governors, so that no single one would stand alone, and preferably they would have previously coordinated their actions and made sure that the attorney generals of their states were on-board with the plan.
We plan ahead for all sorts of disasters. This disaster--moral, legal, and constitutional--should be planned for as well. If the state governors step up to the plate, I believe no small number of their citizens will be heartened and will support them. Moreover, the claim that this is "now the law" will be thrown into question in those states, which will help citizens who do not wish to go along with it. What the federal government will do at that point is an interesting guess, especially if there are several such states. But the mental paralysis that holds that if SCOTUS tells us all that we must go out and stand on our heads this is now required by "The Law" must be challenged and broken.
Any suggestions from my conservative readers of governors who might answer the call?
