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.
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
