Your opening post is very poorly stated. I gather you think the SCOTUS has been getting out of hand ever since the Constitution was adopted in 1787. — Bitter Crank
No question that the OP was slop, but generously interpreting it, there was some truth to it. His initial point did make the point that the Constitution itself never provided that the Supreme Court was meant as a Constitutional Court, empowered with the ability to strike down laws as unconstitutional. They decided they had that power in 1803 in Marbury Madison.
https://en.wikipedia.org/wiki/Marbury_v._Madison . The notion that a court has the power to strike down democratically passed laws is not universally accepted in Western nations today (the Dutch provide their courts no such power and the Finns have a legislative committee evaluate for Constitutionality for example). Jefferson was staunchly opposed to allowing the Court that much power:
"To consider the judges as the ultimate arbiters of all constitutional questions [is] a very dangerous doctrine indeed, and one which would place us under the despotism of an oligarchy. Our judges are as honest as other men and not more so. They have with others the same passions for party, for power, and the privilege of their corps. Their maxim is boni judicis est ampliare jurisdictionem [good justice is broad jurisdiction], and their power the more dangerous as they are in office for life and not responsible, as the other functionaries are, to the elective control. The Constitution has erected no such single tribunal, knowing that to whatever hands confided, with the corruptions of time and party, its members would become despots. It has more wisely made all the departments co-equal and co-sovereign within themselves."

Constitutions are not "sacred" documents like the Ten Commandments--carved in stone and handed down from heaven and valid forever. They are working documents designed to address the perceived problems of establishing government at a given time. — Bitter Crank
And the counter to this position, again quoting Jefferson, "The Constitution on this hypothesis is a mere thing of wax in the hands of the judiciary, which they may twist and shape into any form they please."
What you have done is just what you argued against, which is to make the Constitution sacred in the sense that what it is said to say is the highest law of the land, untouchable by democratic effort. The Justices, under this model, are vested with the power to say what the Constitution says, giving them the power of the gods, to decree what the law that 100s of millions of Americans must live under. Unless you impose some rule that restrains the Justices (like limiting their interpretation to original intent or some other rule), then the Justices can in fact twist and shape their interpretation however they please.
The Kavanaugh fight is evidence of the absurdly powerful role the Court plays in American society, with the left trying to arrive at whatever way, democratic or not, to change the rules to select an all powerful Justice who will swing the Court. The speak of amending the Constitution to eliminate the electoral college so that Republicans can't elect Presidents who will choose Justices. They speak of eliminating equal Senators for each state so that the Senate will not be Republican. They speak of removing Republican Presidents and Republican selected judges through impeachment. The stakes are high and they want their person in power, which means to me that the Court simply has too much power and should never have embarked on its mission to set policy for the American people.
If the net result of this whole mess is that the Court lose it's reputation as being fair and honest, then I say all the better. It should never have been placed where it is, and the day the democracy can assert actual control over the law of the land, all the better.
