Most of them will. One or two liberal states should not be allowed to radically redefine marriage for the federal government when the other 40+ states are appalled at the idea. An amendment defining marriage as between one man and one woman would allow for a consensus throughout the whole United States, rather than let some crazy liberals force this nonsense on everyone. And we should say "no" to marriage by another name as well. We shouldn't be scammed by stupid word games.
Maybe we should let the states decide. Why do we care if one or two go off on a tangent? let them. But we need a law that says we don’t all have to abide by the one or two crazy states lunacy.
