Trump would likely be one of the worst presidents in the last hundred years on any or all metrics, but there isn't any solid evidence to say he could possibly or even wants to create a fascist regime. Many people have no concept of history beyond what they absorb from osmosis, mainly retaining what is convenient to them.
The truth is Trump isn't all too different from his modern day right-wing candidate peers, just with a sense of populist bravado that's mainly superficial (in a salesmen sort of way) even when they are reflected in his few proposed policies (e.g., they all want to crack down on illegal immigration, but he's going to build a WALL) - in fact there's a lot to say from a liberal perspective Trump is measurably better than the 2nd place nominee Ted Cruz on many issues. The insults that separate Trump from other republicans are mainly character-based, because all of the stupid shit he says, but where we can even argue whether he's most racist, misogynistic, or homophobic among his peers.
So, why not call all the republican candidates fascists (assuming people don't already do this)? Sounds like it would be pretty useful in any future presidential race. Why not commit continual political violence against the whole republican party? Whenever there is an anti-abortion bill, an anti-immigration bill, anti-healthcare bill, an anti-transsexual bill, anti-voter bill etc, all of which is happening with or without Trump, right now and in the future. If violence is the answer (as history apparently shows us) why only commit it against lone Trump supporters? Or is the case that only Trump supporters have been successfully dehumanized?
