don't like it at all
but also don't know how we avoid this when people are clearly too stupid to judge misinformation for themselves and that misinformation is actively harming us
Propaganda is disinformation. It has a singular purpose, and is most effective on people either incapable of critical thinking (low intelligence) or people with extreme biases that dovetail with said disinformation (they are not always the less intelligent but sometimes they are - arguably- patently evil, at least as far as the major religious orthodoxies are concerned).
Humans (especially in our world) have grown progressively lazy in regards to discerning fact from fiction and are more willing to basically allow others to tell them how (and what) to think. Several reasons for it, not the least of which is the quest for financial success or security (or even survival); demands on one’s time from family and friends, throw in whatever one does as a hobby or for entertainment and the time necessary to dig to find reality just is not allowed to exist in many peoples’ lives. Too much sensory input to wade through in a sensible way in a few minutes.
So here we are; tell a lie long enough and loud enough and you will convince others it is, in fact, the truth.
