In today's day and age, when most people have access to a plethora of information and a wide variety of news sources,
Stop right there.
You do realise that having such a wealth of information and resources
can actually lead to misinformation, right? There is no one "come here for the actual facts" source - the abundance of various news sites with various agendas, the vast number of pundits, think-tanks, channels, tweets, all of these things make it very difficult for a great number of people to really be able to parse misinformation from information. You can't just put all of this on individuals "choosing not to expose themselves to facts". The situation is more complicated. Being misinformed, especially in this day and age, is not
always a voluntary act.
I can't see that there's anything stopping anyone from accessing other sources of information. If they choose to remain inside an echo chamber, it's their choice to do so.
Unless they aren't aware they're in an echo chamber, or if there are coercive factors preventing them from leaving that echo chamber, or if the internet services they use are set up in some way that actively dissuades them from leaving that echo chamber.
Unless you're suggesting that someone is using some kind of secret mind-control ray or something.
Do you believe propaganda and misinformation influences people? Yes or no?
In a closed society, where internet, media, and press are strictly controlled, you might have a point, but we're talking about media and internet in the U.S. here.
And the US has absolutely no history of media control, bias, or businesses being entrenched in, say, social media?
Come on. Do you seriously want to argue that mass disinformation and propaganda is only a problem because
people are CHOOSING to be misinformed?? If this were true, the solution would be as simple as explaining facts to people. But it isn't, so it isn't.
Don't be absurd.
