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.
Even if the people with Palestinian flags in their bios and handles aren’t well educated on the history of the conflict, what separates them from the Azov libs is that they’re able to look past the official state sponsored narrative of the US. They have the morals and conviction to know where to stand on the IOF genocide despite our media doing everything it can to prop up the American-controlled puppet state in the Levant.
Ukraine is much easier for libs to support because they have massive Western backing and thus get all the positive propaganda they could ever need in the States. It’s hard to take Ukraine flag people as seriously as Palestine supporters because the former have made an identity out of pretending to be transgressive, independent thinkers by supporting exactly what the capitalist establishment has told them to, it’s just so fucking grating
