I know the some are made uncomfortable by comparisons of Republicans to Nazis.
That would be me (although I am suspicious of Elon Musk, specifically).
It is easy to make comparisons between the Nazis and other groups because the tactics the Nazis used were not unique to the Nazis. The Nazis are merely an extreme example of certain tactics. Picking a scapegoat is certainly not unique to the Nazis. Wartime leaders have long known, "The enemy of my enemy is my friend." The United States rounded up the Japanese and put them in camps during the war, but I don't think anyone would describe the U.S.A. during W.W.II. as fascist—at least not any mainstream historian. The U.S. fought against fascism.
What set the Nazis apart from other political movements were the extremes they went to. It wasn't enough to imprison perceived enemies. They needed to be enslaved and/or exterminated. It wasn't enough to establish German military dominance in the region and re-negotiate the Treaty of Versailles. They needed to build an Aryan empire.
I live in Trump country. The overwhelming majority of the people I speak to on a daily basis voted for Trump, and they just want to "keep men out of women's bathrooms" and "keep boys out of girls' sports." In other words, they don't understand the new definition of gender. Ten years ago, virtually
everyone agreed that a boy has a penis, a girl has a vulva, and that's all there is to it. Now there's new definitions for boy, girl, man, and woman, and the conservatives are upset that no one consulted with them first. Ironically, the goal of most Republicans is not to hurt transgendered people. The goal of Republicans is to protect innocent children from being "mutilated" and "sterilized" by greedy plastic surgeons. In the Republican narrative, trans people are, at worst, confused people who need help, or, in the alternative, victims of an evil scheme by greedy perverts to separate them from their money and their genitals. I don't see many parallels to fascism in that narrative, misguided as it may be.
