I'm no Ukraine/NATO supporter by any means, but I wouldn't completely fault random civilians for the rise of Nazis in Ukraine. Even actual Nazi Germany had a bunch of non-nazi people in it (who either fled or were promptly imprisoned/killed, but you get my point). To use your analogy, it's more like the Nazis are in the city, own the government and are a big part of the military and are pervasive in society, rather than physically at every table and not every person will have the opportunity or capability to stomp them out. I sure wouldn't enjoy getting killed by enemies of my government over here, even though I would fully support it ending. Of course, I don't think we should hold this same leniency towards the actual military personnel.

I think a characteristic property of nazism is that it is intolerant and does not allow for opposition, hence the silent opposition has to be careful and smart in how to actually voice or act their opposition given that the nazists are empowered. That does not mean they are supporting them or in any way guilty themselves. They are victims like everyone else. By extension of this logic, everyone living in a capitalist society too impoverished to fight it are capitalists themselves, which is blatantly false.
