Neither.
Ideally, all the courts have to do is acknowledge the truth of the matter -- that the word, 'marriage,' still means what it always has meant throughout history, across continents and cultures.
If the courts screw up, I would not take it lightly.
Beyond than, I sayeth no more.
Well we can't count on those bastard judges so that's why we need the damned amendment!
If the courts decree that "marriage" is limited to the union of a man and a woman, the next thing we'll see is the liberal eggheads in academia advancing the notion that "man" and "woman" aren't genders, but "social roles".
