Disclaimer: I am not pro-Russia just because I am not pro-Ukraine. To me this is a war between NATO imperialists/Ukrainian Nazis and a modern Capitalist Russian oligarchy. There is no good side in this war.
That being said, seeing support for Ukraine from people who didn't even know the country existed a couple of years ago always makes me roll my eyes. It comes across as shallow virtue signalling (even though I hate that term).
Compare it to people who support Palestine. People who support Palestine understand the history of that conflict and that it goes back to many many years of genocide on Israel's part.
People who support Ukraine typically know nothing of the history of the region, it's support for Nazis, it's pogroms, etc.
Even worse, sometimes they do know, they just don't care. 
The best part of when these people still think Russia communist. So crazy how many people have reverted to the same 50s' red scare hysteria that people used to make fun of.
It is pretty clear that international liberalism as a project, despite appearing to be ascendent and dominant, is a completely dead ideology at this point for the ruling class, not much more than a thin veneer for imperialist, chauvinist, capitalism. To be fair, it is unclear if it ever was anything but that outside of maybe the Nixon administration.
As such, those who vocally support it look increasingly foolish and out of touch with reality, not even being rewarded by the ruling class.
