Thanks OP. I'll add something. Your brain is incapable of hearing a false statement without, at some level, thinking it is true. So if you had a true/false statement in class that said, "The sky is purple." You know it is false, but your brain reads this and, at some level, enters the data for "the sky is purple." This holds subconscious sway. Implications are, merely by hearing something said enough times, one begins to think it is true. Which we already know, that's a fundamental of loud liberalism. It's also the reason I still can't hear "Adolph Hitler" without a rush of negative emotions, even though I know he did nothing wrong and was a hero. So, when you read fiction, what happens? When you humor the argument of the other side or read their literature, what happens?
Everything you read gets stored in your brain exactly as you read it, even if consciously you know it is false. If you read enough bullshit, a force builds up in the back of your mind that leads you to be influenced towards believing it. "When you stare into the abyss, the abyss stares back." You cannot read any statement without being, on some level, subverted.
So when the media repeats a lie often enough, it does become "true" as defined as "widely accepted as true." Reality is the territory, but public discourse is the map. If the map does not reflect the territory, people will still believe the map right up until the point they are lost in the woods and starving. People would be more likely to think it's their own fault for being lost and that the map is correct, long after it should be apparent the map is false. So if you take that sentiment and apply it widely to our sociopolitical situation, many things are understood as to mental gymnastics of the left.
Wish I remembered where I learned this from… It may have been sequences by Lesswrong/Elizier Yudkowsky. Yes, he is a jew, but the sequence is hugely beneficial. Just filter out all the cuck shit (oh wait, you just learned you cannot filter out anything!)
This may also be a fundamental as to why memetic magic works. You say Deus Vult enough and people start wanting to Crusade. People believe, ultimately, whatever statement they are presented with, and it takes a lot of hard inspection and mental dissection to isolate and control this effect, which is of course beyond the ability of a normie.
tl;dr brains believe whatever they hear/read at face value, even if they know it is false.
