In what’s left of our country, the Constitution barely hangs by a thread, and in my view that thread has already been severed. Because if one goes by the logic of the Constitution, the Supreme Court has no legislative powers. Those law-making powers were delegated to the Congress. Congress’ limited powers were spelled out in Article 1, Section 8. Making laws about marriage are not in that set of law-making powers.
If that isn’t enough of a guarantee, then there’s the added logic of the 10th Amendment: “The powers not delegated to the United States by the Constitution, nor prohibited by it to the States, are reserved to the States respectively, or to the people.”
This is easy for anyone who can read to figure out (but, these days, being able to read looks like it excludes a lot of Americans, especially on the left): Only Congress can make law under the Constitution. The Supreme Court cannot make law. Congress has limited law-making powers spelled out. Marriage laws are not listed in that set of law-making powers. The 10th Amendment reserves such law-making powers about marriage to the States, or to the people.
All that the Supreme Court did was render an Opinion. Anyone can have an opinion. It’s only a delusion, albeit a rather powerful delusion, that a Supreme Court opinion regarding a power that neither it nor the Congress has is therefore actually a law.
The typical person in the US has no understanding of this anymore. From what I can tell from talking to young people, this is no longer taught in civics or government classes in school.
