Not when it comes to propaganda.
All is fair when it comes to love and war and propaganda is often used in both.
No, that’s precisely the point. Propaganda uses a grain of truth to draw people in, that’s not in dispute. It is designed by definition to mislead people, that is the entire point. It is intended to deceive.
Or put another way “false propaganda” doesn’t sound so bad, comparable to “Free Gift” but obviously there is no point in a construction such as “true propaganda”.
