I said his use of language is reminiscent of the way language was used in the 1930s, I didn't call him a Nazi. For what it's worth, the Nazis certainly don't have a monopoly of using language in this kind of way (creating an "us" vs. "them" narrative), it is quite common with populists all throughout history and certainly not confined exclusively to one particular political spectrum. But every time someone tries to stylize two very complex groups into two simple opposing forces, it should really ring alarm bells.
