For some here "support for Russia" is strong phrasing where it's more like "yeah, I see why Russia did that, and the Ukrainian side sucks ass, but NATO-brain liberals are totally oblivious to that (go figure), but I'm just some dumbass with opinions online so who cares anyway"

As with most geopolitical events, the discussion can't be driven by "[side] [good/bad]" if you want to get an accurate picture of what's going on. Some of what comes across as "support for Russia" is a reaction to the constant westerb-liberal perspective in the media which is a mouthpiece for Ukrainian/NATO propaganda.

I don't speak for anyone except myself (and whoever agrees with me)

The prevailing opinion that I think everyone here can get onboard with is the classic "no war, but class war". The Ukrainian conflict is not a class war, as you've pointed out, and we oppose the continuation of the conflict wholly and as soon as possible (but we are just a meme website, who cares anyway?). If you approach from that perspective it is difficult not to see that this is largely a result of the US (and friends) meddling in affairs it has no business in, and causing an absolute atrocity, not Putin doing a territory grab for no particular reason or whatever.
