History books? Let's look at the French Revolution, often credited with so many great things. The period following it is called "the terror", you can't get more explicit. Anyone reading just that part would want to bring back monarchy, and that's actually what happened. But anyways, for many young people, me included, history books are either stuff to memorize for the test, or something that reads like The Lord of the Rings, but with slightly less magic.

It takes some experience to actually understand what's behind history books, and considering "obvious bullshit" as you call it is the kind of experience that get people to better appreciate history books. At least the ones that are not an excuse for propaganda.
