Do I think that every single member of the GOP is a literal nazi? Of course not.
Do I think that if every single literal nazi was removed from the face of the Earth there would still be a functional GOP party? Highly doubt it.
The overlap is real. Whether you’re talking about nazis, or just old fashioned racists, They are, from an outside perspective, very much so one in the same. I’m sorry that your grandmother had to go through that. It’s awful, and it shouldn’t happen to anyone at all, but if you can’t see the parallels between what Hitler did to the Jews like your grandmother and what someone like DeSantis is doing to transgender people, then you simply aren’t capable of seeing transgender people as actual human beings. Which is exactly what the nazis thought about the Jews.
When the events of Charlottesville happened in 2017 and trump couldn’t bring himself to denounce literal Nazis and had to claim that there were “very fine people on both sides” that should have been all any reasonable person needed to see to be convinced. There is no such thing as a very fine nazi. There is no such thing as a very fine person who thinks that all members of minority races or groups should be eliminated. How hard is it to look at a group of people that only exist to hate and reject them? If you are a principled person who doesn’t share that hate, it’s actually pretty easy. Trump cannot openly reject Nazis and racists because if he did the overwhelming majority of his supporters would immediately drop their support. Even if he himself isn’t a Nazi, the fact that he hasn’t spoke out about them says all that I need to hear.
