The official narrative is so simple-minded it could have been written by a second grader. From Caitlin Johnstone at caitlinjohnstone.com:
The official narrative promoted by the entire western political/media class is that Vladimir Putin invaded Ukraine in February of this year solely because he is evil and hates freedom. He wants to conquer as much of Europe as possible because he cannot stand free democracies, because he is another Adolf Hitler.
The official narrative is that while Russia is in Ukraine solely because its leader is an evil monster like Hitler, the US is in Ukraine solely because its leaders are righteous. The United States is providing arms, military intelligence, and assistance on the ground from special ops forces and CIA officers to Ukraine, as well as implementing an unprecedented regime of economic warfare against Russia, solely because the US loves its good friends the Ukrainians and wants to protect their freedom and democracy.
If you dispute any part of the official Ukraine narrative, you are an evil monster, and a disinformation agent. Because Vladimir Putin is the same as Adolf Hitler, you are also the same as Neville Chamberlain, and are guilty of the cardinal sin of supporting appeasement.
Because you are an evil disinformation agent Neville Chamberlain appeasement monster, it is legitimate to censor you. It is legitimate to accuse you of being secretly paid by the Russian government. It is legitimate to swarm you with coordinated astroturf trolls working to shout you down and overwhelm you. It is legitimate to publish propagandistic smear pieces about you. All normal expectations of public discourse go out the window, because you are a monster, not a person.
