I saw a conversation briefly, I forget who between, about whet | Communism Kills

I saw a conversation briefly, I forget who between, about whether students should just suck it up and regurgitate the propaganda their teachers tell them to get the A, or be actively critical in class. One of the arguments against sucking it up is that once you repeat something enough, you start to believe it. I’m not sure if I think that’s true. What do you guys think?
