There have been various incidents of terrorizing Russian speakers, perhaps the most famous being the burning at Odessa, and in this war the Nazi sympathizers shooting any Ukrainian soldier wanting to surrender, in some contested areas such as Mariopol they may shoot citizens who attend to flee too - aside from Putin's propaganda, I recently saw a first hand account of that by a Greek speaking resident there. As much as it is not widely mentioned in Western media for obvious reasons, Nazis having a real presence in Ukraine is not in Putin's fantasy, and with a few searches you will find both many expressions of that in Ukraine and endorsement/tolerance by Ukrainian authorities. I am not standing by Putin's invasion, and in general stating and inquiring for the truth should never be seen as an expression of opinion. Peace.
