I'll just add this, since I quoted your above question in my last reply to you, but did not answer it in a direct manner. The founding fathers were quite concerned with the possibility of a demagogue ascending to the presidency. One might say demagogues are a type of political disease that can afflict democratic societies. You would not expect one in a monarchy, for instance, since monarchs do not run for their position in society, and do not have to use marketing to sell themselves. They do not have to devise cynical game plans to ascend to power. They're born into power.
The purpose, therefore, was to remind you that there are many styles of political leadership, and the demagogue is among the most dangerous, and something that should be avoided. Therefore, pointing out that Trump is a demagogue is useful information in understanding the situation that exists within our government at this time. And since we are dealing here with the very fundamentals of American governance, the fact that our founders were very concerned with the possibility of demagogues in our future, that fact alone should make one willing to address the question of whether Trump is just such a leader as something highly relevant.
Now, if you choose to say "Trump is not a demagogue", then, of course, the lesson is lost. If, on the other hand, you are able to recognize that he is a demagogue, but would prefer to compare his style to other demagogues altogether, since the leaders of fascism in the 20th century, as points of comparison with Trump, apparently greatly offends you, there are the American examples noted in my last comment. One should keep in mind, nonetheless, IMHO, the wise observation made by Timothy Snyder: "Post Truth is pre-Fascism".
