It would take a lot of people working in concert, with calm rationality, to take apart the emotionalism of organized propaganda.
But, there also has to be something to replace what you take away from the average person in regards to propaganda.
Just destroying propaganda will only leave a a very large hole that will need to filled with something that is lasting. What is that thing? What do you propose to fill the hole that propaganda occupied? Is truth enough, and what will that truth expose?
I too want to see propaganda exposed and destroyed, but those that do the destroying must have something to replace propaganda with.
