To me, and I know not everyone agrees, but I feel nearly all forms of news media (particularly the ones you listed) are way too biased and have agendas to consider the information you consume from them helping you "stay informed and have an educated opinion".
Rather, they're opinion is forming your opinion.
I think it's nearly impossible to stay truly informed these days, unfortunately. I've seen some comments in this thread talk about consuming only boring facts, and I think this is our best bet.
Because most of the time, the truth is boring.
So if you find yourself being negatively impacted, ask yourself if you're hearing unbiased facts, or if you're actually just hearing opinionated agenda.
I also think this is a large root of "the otherside being so stupid". Except it happens to all sides.
