So live in a state where that’s legal. Don’t expect that the Constitution has language that protects your every depraved thought. Or get busy with the amendment process.
That’s the thing though, I don’t see anything in the U.S. Constitution that allows the federal government to legislate what grown adults do sexually in the privacy of their own home. I speak here only of the federal constitution because we are talking about justice scalia. Remember the U.S. constitution for the most part outlines what the federal government can and cannot do. It does not outline everything a citizen can or cannot do.
