Propaganda doesn't totally rob people of agency free will (more accurate term), if it did this site wouldn't exist. People do have the capacity to develop critical thinking, skepticism, and a basic curiosity about the world that allow them to develop some resistance to propaganda.
You can hold people accountable for failing to even attempt to do this.
the quality of propaganda facing me or facing a peasant are quite different as well. People rejecting the divine right of kings seem more like ex-mormons to me than what the :amerikkka: state and corporate media figured out how to brainwash people constantly and consistently.
This is true but also the quantity of easily accessible counter propaganda is greater than ever.
