Intentionally or not, you are doing something we usually accuse our "conservative" counterparts of doing. Several times over actually.
Calling America a Republic, Constitutional Republic, or Democracy is all argument avoidance and degrading things into splitting hairs. But to your point on that line, a Constitutional Republic has nothing to do with handing control over to a Dictator. No matter how we perceive Trump's behavior we did not just wake up one day and end up with this sort of political division by extremes, nor is this the first time in American history we have seen this.
The bigger hypocrisy is what political division has become, and it is easy to argue the furthest left is just as intolerant as the furthest right. In a very terrible and sad way, that is the point of a political system largely ran by two front running but opposing ideologies. 'With us or against us' is the norm, has been. Attacking the ideology of the opposition is nothing new, and it is absent all reality to assume Trump supporters are in an exclusive group of attacks. We may go through periods where those attacks are more vile than others, but that does not remove conditions that created the issue in the first place. Fascism ends up being the ends of both sides, it is also easy to argue that the left has just as much interest in controlling ideology as their opposition does.
At the end of the day Trump being President in the first place, no matter how vile including his background, was only made possible by the DNC putting up an awful candidate and running a terrible campaign. The division created that allowed the 2016 quagmire was not the exclusive handling of Republicans, no matter how much you go with some idea that it is all the other side causing this political mess.
It is a horrible mistake, and wins no confidence in the votes you need, to pretend division oriented politics is all the doing of the other guy.
