The reason [Russia] receives critical support is because it’s opposing the US
From your link:
Critical support is supporting something while also being critical of its flaws. It is often used in the context of supporting bourgeois states that fight against imperialism or are under imperialist aggression.
The thing is, Russia is exactly the polar opposite of "supporting bourgois states that fight against imperialism" or being "under imperialist aggression." Those statements describe states like Ukraine, while Russia is itself also an imperialist aggressor.
You can argue that the US is also bad in that regard, but you sure as Hell can't argue that Russia is any better. Supporting Russia "critically" (which I'm also not buying, BTW: quite a lot of its support around her is distinctly uncritical) is doing nothing but advocating for trading one oppressing overlord for another.
We’re so clear about it that I don’t even understand how you could possibly think we support Russia because we think it’s still socialist?
Thinking that maybe you were still somehow confused about Russia being communist was being charitable -- giving you the benefit of the doubt. If you're saying that y'all knowingly support fascists, that just makes you irredeemably terrible people.
