I can say, based on my own life experience as someone who came from a working-class family to academic education, that the teaching of the justification of violence has been deliberately made in such a way that those in the lower social classes receive the kind of "yeah, hey, violence is always wrong" education from lower secondary and vocational school, and then the academic middle class receives the kind of education where in philosophy classes, the justification of war and violence is discussed quite openly even in text books. Like, no, violence is not wrong. Many positive things like the end of absolute monarchy and the publication of the Declaration of Human Rights produced by the French Revolution are the cornerstone of European liberal society and the rule of law and they were revolutionaries who committed illegal violence in the eyes of the French crown. It's just the gaslighting mentioned in the comment, which emphasizes that those in power now have an arbitrary right to violence. The police and the army are nothing more than the government's protectors. But if you don't consider the government legitimate, then the justification for their monopoly on violence falls apart. Anyone who knows anything about countries where coups or revolutions often occur will understand this.
