I think people are inherently drawn to tribalism and want to fit in/think of themselves as 'good people.' Unfortunately most are not cut out to be lone wolves and maybe some are simply not capable of the kind of critical thought required to think beyond the mantras... I think a better understanding of history could do a world of good. I don't get the sense most really understand what went down in the Soviet Union, for example. Even just re-reading 1984 would probably help people understand where this could all head if we don't push back.
