It will just be “separate” but still “equal” like domestic partnerships were before. Same with mixed race marriages which will be not far down the line. “Leave it up to the states” or whatever, right? “It was never a problem in the 50s”, right?

“Marriage equality isn’t in danger. Were that to change, Americans on the left, center, and right would come to its defense.”

Right wingers would celebrate while liberals and centrist liberals would demand a compromise that involved queer people getting significantly less rights. This should make it absolutely and overwhelmingly clear that “religious rights” mean nothing more than the right to oppress others.
