Let's take the most clear example.
Who legitimately won the 2020 US Presidential Election?
Did Biden win the election fairly and legitimately or not?
Does your position permit "splitting the difference"? How would that work? Are you advocating that we meet in the middle and say Biden won but not legitimately? Or that Trump lost but it wasn't a fair election?
Some positions just don't work like that. OAN won't simply say that Biden is the legitimately elected President. What do you propose is the appropriate "compromise" solution in this case?
The truth is much more nuanced: https://www.adfontesmedia.com/static-mbc/
Most of your listed 'left' news sources only "skew left" but focus mostly on "fat reporting". Compared to FOX/OAN who are "hyper partisan right" and focus on "selectve, incomplete, unfair persuasion, propaganda, and other issues"
When the most important facts of the day (electoral fraud, climate change, pandemic health and safety, vaccinations) have a "liberal bias" - in that the left is on the side of factual reality, and the right is on the side of unfounded conspiracy theories, you simply can't compare the news media the way you have.
