Earlier quoted context omitted.
If the facts can differ then they’re not facts. What you’re then dealing with is propaganda.
Then, we're just back to OP's conundrum: "Everything is opinion." I'll say grass is green and you'll say grass is red, and there can be no fact because they differ.
The colour of grass is something that’s scientifically measurable.
My point is that some broadcasters are very strict about sticking to the facts. Some will misrepresent those facts but not technically lie (eg discuss statistics that favour their partisan view but don’t share the full context behind those stats).
And then there’s broadcasters like Fox News that promote flat out lies. It’s often not even an interpretation of the truth. It’s shared as an opinion but the evidence clearly proves it’s just lies presented as facts.
And I really wish there were criminal charges for broadcasting blatant lies. Not just in America, but most of the developed world where populist-propaganda is used to brainwash gullible voters.
