Earlier quoted context omitted.
The problem isn't you, but others who do not try to curate their own diverse sources. When time comes to make democratic decisions, if those who are influenced outnumbered people like you, there'd be no way for you to make your case and convince the others of your correctness.
Is it really a healthy democracy if the flows of information are controlled from the top down? If I provide you with a tuned set of information in which everything says what I cant, I can get you to believe whatever I want. This is just changing the source of said influence, not removing it.
but the facebook/social media isn't "controlled from the top down" - it's people deliberately choosing to _only_ consume them (thus giving those media companies defacto control over people's tuned set of information sources).
I'm saying that most people don't care enough to look for separate sources and do their own critical thinking.
