I don’t speak for everyone here, but the prevailing attitude I see from most communists I associate with is not one of overt support for Russia. I have occasionally seen misguided nostalgia for the USSR, which the Russian Federation is not, but it isn’t common.

Not supporting the US via a proxy war, or NATO, or Ukraine does NOT mean supporting Russia. A common misconception liberals have is everything must be black and white, us vs them. If you don’t support X you must support Y. In their minds, everything must be a simple “good guy vs bad guy” dichotomy. That simply isn’t true. When two imperialist capitalist countries are at war, we should only strive to encourage a peaceful resolution as soon as possible for the sake of the actual people affected ((EDIT: Just to clarify since I realized I might be unclear here, I am speaking in generalities. I don’t think this particular invasion has imperialist undertones, there are many more other underpining reasons it started). Supporting NATO would only serve to escalate and prolong their suffering. If they truly cared for anyone in Ukraine, they would not have repeatedly blocked attempts at signing peace agreements.

We understand a lot of the underlying justifications for the war and the provocations that led to it, but again that does necessitate cheerleading for Russia either. It just means we know that Putin did not wake up one morning and randomly decide to invade Ukraine for fun.
