There's no drama, but people like the simple explanations of the world. USA: good, North Korea: bad. USA propaganda: justified, special, exceptional. non-US propaganda: suspect, biased, evil. So being confronted with the idea that they're simply a little bit blinkered (not totally brainwashed, just a little ignorant) and that history and current events involves more complexity and nuance causes some people a bit of discomfort.
