We live in the year 2022 not 1822.
Most Russian soldiers knew damn well that Ukrianian Nazidom is a pile of bull.
Hell many Russian soldiers have relatives in Ukraine, part of why so many deserted on the spot the first days.
The ones that chose to indulge in all the looting killing and raping certainly did not do so because lol Ukrainian Nazis.
Do you really think that everyone alive right now lives mentally in the same century that you do?
To Russians "Nazi" just means "opposes Russia". They don't actually teach about Nazi atrocities like the Holocaust in school, I understand; the Nazis were bad entirely and only because they attacked Russia. Which is why the Russians don't see any conflict between calling their enemies "Nazis" and acting like Nazis; the majority of the Nazi behavior and worldview are admirable and to be emulated by Russian standards.
Ask people from just about any European country that was invaded and occupied by the Germans in WW2 about the Nazis, and they will probably answer first in terms of what it meant for themselves as a people. The Nazis did not restrict their atrocities to any one group. They did some horrible stuff to all sorts of people, just not in bulk quantity like they did to the Jews.
Ukraine does have dozens of right wing paramilitary forces. And the Ukrainian Armed Force don't actually worship any kind of Goddess either, even the anarchist groups don't do that.
The religion that worships a "mother goddess" figure is called Roman Catholicism. Just saying. Not that I give any credence to their silly theory about the causes of gender decadence.
