>The US is one of the most heavily propagandized populations in history.

I see this statement repeated often with no supporting evidence. Seems a little ironic!

Is this claim falsifiable?

Would you be able to name the 2nd or 3rd most propagandized populations, in your view? Do you know anything about propaganda in e.g. the USSR or North Korea?

"Historian Sergo Mikoyan claimed that decades prior to the early 1960s, offices and stores had to submit papers with examples of their typewriters' typeface to local KGB branches so that any printed text could be traced back to the source, to prosecute those who had used the typewriter to produce material deemed illegal. With the introduction of photocopying machines, the KGB's Fifth Directorate and Agitprop Department required individuals to get authorization to use printing office photocopiers to prevent the mass production of unapproved material, though restrictions could be bypassed by bribing employees."

That's what an actual heavily-propagandized population looks like. Meanwhile, I can open up any social media app and be greeted by a sea of anti-American slop.
