funny how you didn't call out the OP and ask them for "some additional arguments backing" up their claim that the Iranian TV show was propaganda, but here you do when its American politicians.

Isn't that a bit hypocritical?

as for context, a good book on the subject is "manufacturing consent" by Noam Chomsky. In it he details how american media of all forms is used as a propaganda vehicle in order to shape and create the american public's politics.

The TV shows linked are just applications of that strategy.
