Great questions you're raising in this post. The deeper the media propaganda is, the deeper the pushback and delusions are.
Something that came up for me is the contact theory news article we summarized, specifically how that can be applied to the media landscape. I might be idealistic with this, but I feel like major change can happen if we just had mainstream media platforms start representing all views and role modeling public debate/discussion. Like if the gov were to bring back the Fairness Doctrine, which requires media organizations to present all sides of controversial issues.
I feel like we don't need the majority to change their ways in order to create significant change in the system. We just need a movement big enough to change the spaces where most people put their trust/authority in. Then the small percentage of people that think delusional things will be less noticable.
