Some households even ban TVs and mainstream news in their homes.
I hold just the opposite position. You must know your enemy and their positions as they attack you. Blindly ignoring their words makes you ignorant, not wise and strategic.
I'm saying it's okay to learn from ALL sources, even those sources closest to the politicians (mainstream news sources).
Not because it's good for you, but because you need to be able to see the bullshit and fearmongering and statist nonsense, and be able to point out the flaws in their "logic".
Brainwashing and conditioning usually comes, not from hearing all sides, but from only being indoctrinated by one side.
I may be a liberty lover but I still teach my friends and family about socialism and fascism and communism, not because I think they should become those things, but because I want them to be able to systematically counter their horrible and erroneous arguments.
The more we ignore other viewpoints that compete with ours, the more ignorant we ourselves become.
Once again, don't watch the news to become indoctrinated, but if you do watch the news, that's the best time to question their diatribes and to logically work your way to their flaws. Always dig deeper to see where their sources are biased and where their reasoning is fallacious.
This is why I'm not a libertarian household that bans people watching the news, and if anything watch it with them and explain why I personally agree or disagree, and try to use empiricism to back up my positions. I feel the more educated people are on all sides, the easier it'll be for them to see why liberty is the correct answer.
Don't fear educating people on all sides, but instead realize the harm that comes from only presenting one side.
