The first thing that caught me about your comment was this: as Chomsky says, "If you don't behave in a dictatorship, they'll just bludgeon you over the head."
Ignoring the appeal to authority (which always is a red alarm for me) the problem is that dictatorships are completely different entities than are commonly thought. Most people think that in a dictatorship there's one guy in charge and he directly controls the lives and actions of all the people. But that's not true: simple span-of-control theory says that one person, at most, can observe and coordinate the work of 5 to 10 other people. The more control, the fewer number of people. So there are dozens of levels between Kim and his people, each level interpreting things their own way and each level impacting how things are run to a great degree.
Nope, dictatorships are actually oligarchies, with a symbiotic relationship between the dictator and the "middle management" so to speak. Even if the dictator took all the middle level management out and had them shot, there would just be a new structure put in place with all the same old problems (and symbiotic relationships)
My perception of your comment kind of went downhill from there. Some highlights were comparing "news shows" across several different channels, 1 of which was a news show, 1 was a quasi news show, and 1 was an entertainment show. I seriously doubt such comparisons are going to lead to much value for the reader.
Then we had the whole problem of definitions. As I understand it, propaganda is the dissemination of information in order to effect change in public opinion. It doesn't have to be false, involve logical fallacies, or any of that. Some of the best propaganda, as the Pentagon says itself, is simply telling people the truth about stuff they haven't heard before.
Then there was the over-reaching narrative of "everything is propaganda" -- joining up marketing, entertainment, sales, etc. It's a sign of a poor definition when it fails to distinguish things. And of course we had to trot out a good dollop of American-bashing with the Creel commission and such. Sometimes I think America-bashing has become the salt and pepper of faux intellectual discourse. Discussion getting a bit tired? Throw in a few jabs at the Yanks. "Easily manipulated into warlike frenzy" and "more controlled by propaganda than North Koreans" (I paraphrase) are serious assertions. Assertions that you began with, then failed to offer any proof, aside from a Chomsky quote.
So apologies if I am being a bit harsh. I just didn't get much value from your comment at all.
