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.
i assume the majority of people who 'dont fall for the propaganda' had really easy lives. and it's funny how right wing is the viewpoint that you're better than someone for being left wing.
