"American culture is working hard to undermine the assumption...."   What  on earth does that sentence mean?   American culture pushes and pulls in all directions.  If it goes in a direction that you don't agree with, it is still American culture.

"This shift in our collective psyche has been so profound that not even the “great men of history” are safe on their pedestals."  What shift in collective psyche?  There was no shift towards your collective psyche. Your collective psyche is same as it always was and it lost the election.  What you might want to come to grips with is that a large part of America has no idea what you are talking about when you talk about your collective psyche. They are not buying into this kind of gobbledygook.

Sorry I have no empathy for this kind of insular writing and thinking.  But I do have passion or compassion for many of the issues that concern you.
