there is a difference between censoring dictator-state propaganda and censoring single citizens.
On top of that, let's add that official state opinion about something (especially about war enemies), with punishment for different opinions, is typical of totalitarian state. In democracy one would have the statement of the russian dictator publicly commented by joirnalists. Here we have cancellation of statements. And this applies down to single citizens. Are we dropping our rights down the toilet? Anything makes you think this will be limited to russian war? How would you elaborate an informed opinion if everything gets canceled?
