The state promotes violence by the state, and being docile for the citizen.
What media are you consuming? Take a look at any list of top-grossing films of the past few decades and it's riddled with non-state lone wolf actors using violence to solve their problems.
You're saying that John Wick, Creed, Spider-Man, The Fall Guy, Furiosa, Venom, etc. are teaching Americans to be pacifists?
