I feel like this kind of reductive language isn't helpful. They are nazis in the sense that mstters.
Nazi has for a while been another word for fascist, or at least a particular brand of it. The Republican party as a whole has slowly been moving in this direction my entire life.
Trump being too stupid to play the long game managed to build a cult around him by speed running fascism, but there is nothing he stands for that the Republican party hasn't had a long hystory of standing for.
People denying the facism is how we got here.
Sounds like a great use for LLMs.
