I've heard Israeli call Hamas Nazis, Russians call Ukrainians Nazis, Ukrainians call Russians Nazis, random political figures calling other equally random political figures Nazis... Now I'm sure it's sometimes called for, as you said, neo-nazism, for whatever reason, is a thing. I feel like it's the same crap as calling any idea a tad on the left "commie" or "tankie". It's not a valid criticism to put everything under a blanket term, I would much prefer that people put reasoned arguments before irrational name-calling. But sadly politics is all about appeal to emotion, isn't it? I feel deeply ashamed when I watch political "debates" in my country.
