Congrats, propaganda has accomplished its primary objective. Convincing the population is a secondary objective. Its true goal is simply making the populace apathetic so that the regime can carry on with whatever it wants.
Do you mean not trusting every single aspect of a book? Or do you mean trust without validating it?
Otherwise I don't understand how could anyone ever learn about history that way.
So you are saying that lies by Putin's regime, which lied from day one are the same as some moral boost bullshit of the country that is attacked by much bigger country?
Relativize and conquer.
Well, lucky you, you can go to Ukraine to check whether corpses of children and women massacred by Russian armies in this war of aggression are real. you don't have to trust a book.
