No one's arguing for lawlessness. But the government shouldn't pass laws proscribing consensual behavior in the bedroom. That's part of one's inherent liberty and privacy, natural rights that deserve protection by the Constitiution.
No, state and county/parish have long held authority,
as it should be - The grand experiment left anything not expressly given to the federal government to the states. If you don't like the morality of the Bible belt, go live in Californica... And the states have traditionally tried to hand such things down to the county - If you don't like rural values, go live in the nearest big city...
Moral and legal guidelines have never been meant to be universal. But that is what's happening now. Immorality, legislated at the federal bench, is shoving big-city values on all of us, whether we like it or not.
