Ok so make that case. What specifically is he doing, what mechanisms is he using, what does the trajectory look like? Because that’s an argument worth having and I’d probably agree with a lot of it. But “this is a Nazi before he gets into his stride” is still just the label doing the work instead of the argument. That’s my entire point.
I’ll grant you he’s a Nazi sympathiser, there’s enough evidence for that and its easy to lay it out. But that’s the argument you should be making, with specifics, not just calling him a Nazi and leaving it there. Because the specifics are what actually alarm people. The label just lets them dismiss you.
Wide reaching propaganda that advocates for a white ethnostate (this alone is enough), explicit displays of Nazism with the heil, financial support to white supremacist parties in the US and abroad.
