I understand your point, but I think the logic you are presenting is what is enabling these people. Ask yourself - what is the nuance in the Ukraine war? Fence sitting, and talking out both sides of your mouth about how we should condemn Putin yet also accept there is nuance to these issues is dangerous. It's not complicated. If you don't condemn Putin's actions, you are implicitly accepting/agreeing that Ukraine should be wiped out.
Putin relies on the populace accepting that there is "nuance" to the Ukraine war. Russia has conditioned (or at least is trying to condition) the population (in the west) into adopting this logic but the reality is that there is no nuance to this issue. What nuance could there be to an aggressor invading someone's land?
They are almost certainly a Russian troll. See their comment history.
