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 can either understand why people in my life believe that Putin is Hitler 2.0 and it’s our moral imperative to kill all Russians, and work against that narrative, or I can denounce them for having common brainworms that I (and most of this site) held until a few years ago.
Or are you talking about weirdos online?
