What is your assessment of the propaganda argument?

Propaganda is the more or less systematic effort to manipulate other people’s beliefs, attitudes, or actions by means of symbols (words, gestures, banners, monuments, music, clothing, insignia, hairstyles, designs on coins and postage stamps, and so forth). Deliberateness and a relatively heavy emphasis on manipulation distinguish propaganda from casual conversation or the free and easy exchange of ideas. Propagandists have a specified goal or set of goals. To achieve these, they deliberately select facts, arguments, and displays of symbols and present them in ways they think will have the most effect. To maximize effect, they may omit or distort pertinent facts or simply lie, and they may try to divert the attention of the reactors (the people they are trying to sway) from everything but their own propaganda.
