It's worth noting that being propaganda by definition doesn't automatically make something evil. Propaganda is anything intended to sway someone's opinion to support a cause. Every political campaign ever is, by definition, propaganda, as are the actions of any religious person trying to convince anyone that their beliefs are right. It doesn't have to be a conspiracy or a scheme or use manipulative or dishonest methods to get the point across. It just needs that intent to sway the opinion of those it reaches.
