It depends if you want to avoid the mainstream media just get your sources on the USA from other countries where objective reporting still exists.
Nhk Newsline from Japan, the BBC at times in the UK they are far more bias to Brexit , CTV or CBC from Canada, RT is pretty honest despite all the US fear mongering about it being the Kremlins shouting point from Russia, Al Jazeera from the Qatar,Dubai or CCTV from China to name a few.
The point is as long as it's not from the USA it probably is ok to watch news related to that country through it and not feel like being hit by endless propaganda waves.
Just be careful not to do the safe-space logic where everyone lives in filter bubbles that is a scarier thought than 1984 and the thought police, it would be the self-created thought police.
https://en.wikipedia.org/wiki/Filter_bubbleThanks for the link to that Wiki page - it gives me a name for what I am trying to describe, my 'filter bubble'. I'd like more control over my own filter bubble.
I'm cool with being in an isolated culture if the alternative is being overloaded with junk.
I'm in the UK, I do pick through a few of the news sources you mention but I can tell you that the BBC are always pushing their narrative.
My favourite news source is probably the Financial Times, because they attach less emotion and/or fear mongering to the stories.
Don't have much experience with US news outlets....
