Everyone has a bias and skews stories, also, creating fear probably increases viewership. If the media always said everything is fine, less people would watch IMO.
I understand the sentiment, and I'm also careful about how much news I consume, but there's a fine line between this and being privileged to be able to afford to skip news because those suffering aren't your family.
In a less extreme example, if a big project came into your neighborhood to destroy all the houses on your street to build a highway, I'm sure that suddenly this news would make you want to get involved politically to advocate against the destruction of it. But when that happened in the other neighborhood and you didn't care to even write an email to your local politician to oppose it because you didn't know about it, other families suffered.
It's a fine line.. I've seen my parents watch news 3 times a day (lunch, dinner, and late-evening news) and it was definitely not healthy and did not make them better citizen either. I don't have a perfect answer.
I don't think there's any obligation to keep up with events on the other side of the world (or the other side of your country) if you're not also able and willing to do something about it. I dunno about applying the "privilege" label to that—in fact, the fewer resources you have, the less point there is in it.
Things that happen across the world affect us here too. Maybe your friends have family in Ukraine or are from there. I have students who are Ukrainian. Currently Ukrainians are leaving their homeland as refugees and resettling all around the world. They could be moving in down the street and will be your neighbors! Knowing what's happening around the world allows one to be empathetic to the situations of others.
Being an American is like being a Roman citizen; you have to run the whole empire.
Again, I think that end would also be better served if a high proportion of news media consumption were shifted to citizenship-relevant books (and maybe very high-quality, low-frequency periodicals), probably starting with textbooks and classics in political science, history, and economics (I doubt anyone who's mined those well already, needs any help picking their next high-value read).
Nope, not my duty. My duty is to elect politicians who enact policy affecting me. If a politician enriches my country at the expense of another, it is my duty to vote for him, for the sake of myself and my family. No one is a citizen of the world.
Watching the news is not helping these people.
Hence why I said most. I definitely agree that being exposed to outside events can be important for sympathizing with those affected (and possible helping them), but at the same time, one does not need to be aware of everything going on in the world.
