The world is not full of idiots, rather communication channels are heavily managed to prevent people from establishing consensus around the obvious.

No matter how many people think press release X is obviously wrong - 80%, 95, 99% - it'll always be "the comments section criticizing the article," or "bloggers sharing incisive criticism."

That rather implies the world is full of idiots.

If you know how your emotions and opinions and neurology can be used against you and don't use that to inform your media consumption habits then that's just stupid.

There's no safe way to watch propaganda. There isn't even a safe way to watch it secondarily: an endless stream of debunking videos pretty quickly still does the main thing propaganda needs: repeats the core message.
