Boomers were all raised with the mindset that
1) journalists are all trustworthy, selfless and borderline superhumans (an impression that is reinforced in FAR too many works of fiction)
2) that everyone had a "duty" to stay informed and up to date (an impression reinforced by TV networks themselves, i.e. "this is what you need to know about x")
So they watch TV all day without question, and basically brainwash themselves.
I don't mean to dunk on an entire generation like this but its actually fucking sad. They're human beings who have been manipulated for so long they are blind to it. I talk to my grandparents and other older relatives and no matter whether they are left or right, as soon as anything related to current events comes up in conversation, they turn into zombies mindlessly regurgitating what they watched.
It kills me inside because they let that define them, and they're so set in their ways that nothing I can say or do will change them.
