We elect men into high office who don’t have a functional moral compass. Its hard to find a structural answer to that.
The only thing that works, is for people who do have a functional moral compass to push back.
Hard, but not impossible. Certain structural amendments could leave these amoral, unprincipled politicians with a tad less wiggle room....
To your second point, the need for popular push-back to the horrors perpetrated by this illegitimate Court. I've been thinking a lot about that lately.
To me, the main point is: Ours is a system of government that rests entirely on the consent of the governed. If a citizen complies with a law that is null on the basis of the Constitution, then it can be presumed that he has given his "consent" to it.
It seems to me citizen "push-back" necessarily entails widespread civil disobedience to such a law. But the citizen must be prepared to bear the "penalties" that would be sure to follow....
