Not that funny really. A Nazi is a person following a certain ideology, which takes only one level of generalization to imagine a Jewish Nazi being Nazi to Germans, Poles and Frenchmen. One level is not that much.

And references to German Conservative symbols are kinda popular among Ukrainian nationalists. Poverty and shitty education through the years of independence do that. Not much different from Russia itself or many other former Soviet republics (somehow European, of course, it's hard to imagine a Nazi Uzbek or Tajik, but Tajik nationalists love Achaemenid empire and Samanid kingdom very much) or even former Warsaw Pact countries.
