Perhaps
@harms can give us his opinion on the following topic. From youtube videos like the one below, I get the impression that there is constant propaganda in Russia that "truth is relative", and "we cannot know the truth". And many people have genuinely accepted that. But if one accepts that "we cannot know the truth" then they can also claim that the authorities are not actually lying to them (since it is impossible to know the truth).
This video is just an example. It seems that the majority of Russians do not know that the Soviet Union was occupying the Baltic States against their will. It also seems that the majority of Russians do not know about the Molotov-Ribbentrop Pact and that Stalin actually had a friendship agreement with Hitler. This is not "just ignorance of history", I get the feeling that many of these people do not believe in truth and in reality and in facts, like everything is a matter of opinion. Or do they just pretend so?
