My guess is that no one in the Trump White House has ever read Crevecour or his definition of what an American is.  Whether Trump is using Steve Bannon or a fellow traveler is still up for debate, but the fact that he believes that being rich is an excuse for being coarse is proven out by his visits to Howard Stern (unless he really is simply building a brand).  Traditionally, leaders mitigate against the worse angels of our American nature - forming a barrier that respects the Bill of Rights more than the people themselves do (although the pandering by otherwise urbane Southern politicians to the racism of much of the populace shows that there are limits to this).  It is not the pro-choice or pro-LGBTQ that are a threat but the alt-right. Trump has no desire to hold off the masses.  He and his alt-right attack dog, Bannon, delight in pouring gasoline on their burning cross.  The question is whether people of faith and good conscience are willing to stop them.
