Frustrated beyond words that so many years since March 2022, liberals still believe the reason communists are in favor of the SMO is because communists think Russia is still socialist. If 3 years isn't enough time for them to understand (not necessarily agree with, but understand) an argument as simple as "NATO holds back world socialism; Russia's war in Ukraine is fundamentally about pushing back NATO; therefore it is good for those who want to see socialism bloom if Russia succeeds in exhausting a NATO effort to expand into Ukraine." It makes me seriously question that any significant number of people are ready to seriously dig into criticism of capitalism, participate in the development of counter-counterinsurgency tactics, and all the tasks that are necessary for a revolutionary movement.
The upshot is that, much like liberals and reactionaries don't believe their own propaganda but repeat it anyway as a means of positive moral and mental affirmation about their place in the world, they also don't necessarily fail to understand the argument, but understand it perfectly well and just refuse to interface with it because of cognitive dissonance. This is also true of anti-masking, it's not that they don't understand the necessity of still taking precautions against COVID, it's that doing so would cause them to take on a counterhegemonic position that breaks from the reality they see around them and they'll be socially punished for breaking uniform.
That last bit is strategically relevant because it means it's possible to beat these people's head out of the sand if the hegemony of the liberal and reactionary ideas is itself challenged (not just the specific ideas themselves). This is difficult because it requires severing people from their currently established consensus reality, but I think we all know the world is breaking that down without our help at the moment anyway.
