It's apparent the homos will have their way on this.
Out best hope is to ensure it's decided on a state by state basis, saving a few states rather than losing the entire nation.
That said, I don't believe this issues will survive a USSC decision. They are likely to rule the 14th Amendment dictates homo marriage wherever state sponsored and recognized marriage exists.
It won't be long.
We should all be asking ourselves: How does this harm me and mine? How do I protect me and mine?
My prediction is that if we ever come to the point where gay marriage is legal in the whole country, five years later the divorce rate among gays will be higher than that among straights.
