Where does this idea come from? That the constitution was "written for normal human beings"?
I mean, it was certainly written for humans, by humans. But it was written by humans who were (generally) studied in significant philosophical concepts and practical organization of government. It was written at a time when "normal human beings" were illiterate. It was written for well-educated people of the time to read and understand. I think it is John Adams' personal library that is in the Library of Congress. It is an AMAZING collection of books on topics from all over the world. It reflects a knowledge of, and interest in, very complicated ideas.
And that totally ignores the role of SCOTUS in the actual constitution.
Now, the Federalist Papers... that marketing campaign may have been designed for people to easily understand.
And if SCOTUS decides the constitution is just a piece of paper and that they'll no longer defend it against legislation, are you saying that you support their authority to do so and will bend the knee if it comes to such?
