Nonsense, as much as I disagree with it and think of it as an abomination of Federalist principles, the decision of SCOTUS on gay marriage is unfortunately legal and the law of the land.
Like it or not, SCOTUS is the final arbiter on what’s Constitutional as long as they have subject matter jurisdiction over the dispute (which they do).
The only ways to change that is to either pass a Congressional statute taking away said jurisdiction (and create a Constitutional crisis most likely) or amend the Constitution restoring traditional marriage as it has been from the beginning of time.
SCOTUS does not make law. Your ignorance of grade school powers of separation is appalling.
