People can be easily brainwashed. For example, many have been convinced that an invisible man lives in the sky, or that a changing climate is an existential threat; if it’s said enough times by authority figures with no countervailing message. Even with the presence of a competing idea, one with superior logic & merit, once the indoctrination window is past, there is no changing anyone’s mind. That’s why elections are always so even; no matter what happens to either side, however much good or terrible, it won’t change anything. This is certainly a huge weakness of democracy, possibly a fatal one, and something the propagandists understand; getting their message across during the formative period; for children that would be public school, or adults, that would be their introduction to a new concept. The Left has recognized this basic fact for decades, while the Right remains blindly docile while it happens to their own kids.That’s because the Right believes in live & left live, at least as long as it’s not pushed into their faces. However, the base emotions of envy, resentment, exploitation & narcissism, something the Left is susceptible to, keeps them from simply minding their own business, rather than proselytizing their message to vulnerable listeners, utilizing propaganda to mold & control the public zeitgeist. At first glace, it seems all bad, but there is a difficult conundrum because only brainwashing can suppress people from acting on their base emotions, so it’s not something that can be ignored. The Right must fight propaganda with propaganda.
