You are absolutely correct, black robed tyranny is tyranny no less because it is erudite. There is nothing in the Constitution which says the Supreme Court shall pass on the constitutionality of these matters nor is there anything in the Constitution which makes the Supreme Court the sole arbiter of these social issues. To the contrary, as your reply points out, the power is within the People's House of Representatives in combination with the Senate to restrict the appellate jurisdiction of the Supreme Court and keep it away from these issues.
The fact is the political parties have not been able to overcome the inertia, the aura of rectitude to which the American people have been acculturated to defer. But I system is designed to act to correct error, rarely to avoided, and to correct error only when it reaches the threshold of the intolerable.
All of this mindless support for Donald Trump is part of the reaction to the elites, on the court and elsewhere, pushing us past that threshold. There are other, better ways to rectify a system that has lost its balance than with the imposition of a mountebank in charge of article 2.
But if Congress becomes filled with cowards and “go along” sellouts, and the POTUS rules by decree, and the future cultural Marxist SCOTUS backs him up, then we have become the USSR, which also had a pretty Constitution, on paper.
I don’t see an outbreak of courage in Congress, so it will be civil war instead.
