My post was only partially in jest but thinking about it on the way home from the Big Apple tonight, I think the best thing would be language that limited the power of that branch of government commonly known as SCOTUS while acknowledging that tenth amendment issues are the province of the states and the people occupying them.
The fly in the ointment is exactly what you pointed out. I am concerned that an ultra minority, eg a small state, can decide the issue for the entire country on it's own through that full faith and credit thingamabob.
You're task, if you decide to accept, would be to come up with precise language that would satisfy both you and the social troglodyte, that's me.:-}
Good luck!
