The question is whether a nation filled with people who believe in propaganda is a nation that can survive. Also, what is the duty of those who know the difference between truth and propaganda to do about it given that those who do not know would crush the truth if they could. I would suggest that at a very minimum no commercial entity that avails itself of the publically owned media of data transmission should be allowed to broadcast opinions of single opinion origin. For example Hannity, should not be allowed to broadcast without immediate rebuttal by others that he is a lying propagandist. He should be allowed to speak but only with immediate refutation by other opinions.
