Civil marriage is created and administered by government - how do you propose government not "dictate" it?
ooof. Right after you tell me where that power is enumerated, I’ll answer your question.
He is saying at the fed level. Marriage, abortion, guns and many are all suppose to be off limits for the feds. They are not in the Constitution and should be handled by the States; we should not encourage the feds to do what is not part of their approved powers.
