I am not being sarcastic at all. It is a common misconception that propaganda means lies. Propaganda is information designed to get you to believe a certain thing or feel a certain way. The best propaganda uses entirely truthful statements to manipulate your beliefs and emotions.

One of the best examples of this were the endless photos and information about stocked store shelves, filled with fresh goods at dirt cheap prices, during the Cold War. In general truth is the best propaganda, because when you lie there's always a rubber-band effect when somebody realizes, sooner or later, that they've been had.
