Yes, I know this. However, in this age of easy information and knowledge about other societies readily available it becomes more a matter of willful ignorance than being duped by propaganda.
You aren't familiar with the propaganda if you think folks duped by it would consider "other societies" with anything other than fear hatred and contempt. The problem with "do your own research" is confirmation bias.
If I knew, I'd already be president? The only thing that seems to actually work is slow, one on one, patiently and empathetically working with people where they are. Mass media only seems to be effective at sowing division.
Maybe things were different under the Fairness Doctrine? I don't know.
Counter-propaganda isn't the answer. We've already got counter-propaganda, from the other political party. It's not persuading anybody who doesn't already drink that flavor of Kool-Aid.
No, I don't have an answer either. I just know that counter-propaganda isn't it.
Well, as I said, in my opinion people can be blamed given the readily available information and in regard to the multi-decade irrational fear of socialism. Willful ignorance is a thing.
