It's less that many of us are espousing support for Russia, but rather opposition to the propaganda and for-profit warmongering by the West that has been born from the conflict. There was an excellent post earlier today that provided a great take on how to view the war through a historical lens - I have my own disagreements with some of OP's points in that thread, but luckily the comments there cover those disagreements pretty well from a good leftist perspective as well.
EDIT: wait lol I see you already commented there, nevermind
Let's be realistic, "centrists" are just right-wingers who would prefer the racism be less overt and that the poor die out of their sight instead of openly in the streets.
