My point is that Nazis in the Ukraine isn't a new thing and you can't justify their position in the Ukrainian society by the ongoing war. They freely marched with torches on the streets of Kiev before anything happened.
"theres similar marches in Russia too"
Not really, Russian ultra-nationalists are suppressed under Putin, some of their leaders are in jail and their organizations are designated as extremist. There were so called Russian Marches, but no more.
"does that make all of them Nazis"
Yeah, people marching on the streets with torches and shouting nationalistic and supremacist slogans are nazis, be it in Russia or Ukraine. Doubly so if they carry the portraits of Nazi collaborators and perpetrators of genocide. Slogans 'Ukraine above all' don't help either.
My brother in christ, the head of the main PMC in Russia has Nazi symbols tattooed on him and named his PMC after Hitlers favourite composer.
Nazis aren't suppressed under Putin, they are actively hired by the government.
