I do not think you hit on any of the things that make Trump a potential danger to our system of government.

It is his blatant contempt for our Constitution, rule of law, and our political traditions that makes him an existential threat. Support for torture. Jailing political opponents. Wanting to jail journalists saying things he doesn't like. Making religious tests for entering the country. (Many more I'm sure I'm forgetting.)

I think way to little has been made of this as the key reason Trump is not fit to hold the office of President.
