The Capitalists had been well prepared in advance, they were pushing and pushing, surrounding Russia with missles, ETC, such that it was only a matter of time before Russia would need to act to protect itself, since the populace of Capitalist countries had been successfully kept completely in the dark about that building situation, they were well prepared to paint Russia’s actions as out of nowhere, sudden and vile “those evil evil Russians”, they showed manufactured atrocity propaganda and went into overdrive with, stuff like, taking things that the azov/keiv regime did to donbas or simular, and passing it off as stuff Russia did to the ukraine for example.

On top of that, the more emotionally supported a belief is, the more painful it is to acknowledge that it is wrong, since the atrocity propaganda had so traumatized liberals, and since they got so drawn into emotionally supporting what turns out to be a fascist state color revolutioned in by the US, facing just how badly they were made the fool, and their emotions played like a fiddle, for many liberals, facing that is brutal, so they go into denial instead, it is one reason why they may support the Palestinians, but condemn Russia.
