In the replies and the quote tweets, there are hundreds of people saying "Sure it's good to accept refugees but if Russia's neighbors take them in, then Russia will eventually invade."
On top of this are all the replies you'd expect, like "Russians are all responsible for the war" ( I guess Russia is no longer an Evil Authoritarian Dictatorship where citizens have no say.)
If you're a Russian, you watched your entire superpower status collapse under the auspices of the West with the promise that you'd be able to share in the abundance of their brands and supermarkets. Instead, America kneecapped even a half-measure liberal democracy and installed a dictator who bombed parliament and privatized resources, destroying any stability that was left in your life. Americans were only happy when you were living in rubble under a democracy that was obviously a total sham to anyone who looked at it.
Instead of destroying NATO once the USSR was gone, they expanded it to get as close to your border as possible and sponsored a fascist coup in Ukraine to end the moderate status quo and install an explicitly pro-west one in its place.
Now, even the liberal, pro-West Russians who don't want to fight in the war and don't support it are called orcs and subhumans. If they try to flee to one of these vibrant liberal democracies to avoid conscription they'll be called orcs and treated as second class citizens, often people who call themselves leftists (don't laugh!).
If I were russian, the only conclusion I could come to is that Westerners hate Russians because of their nationality. I think this is why so many support Putin, because what other option makes sense if you're subjected to this. Of course that's only partially true, Putin is bad and the war is wrong, but I might think differently if I were russian.
