Bret Weinstein talked about his direct experience with that in a recent appearance in Vancouver. How left-leaning and right-leaning publications reported his story differently and to varying degrees of accuracy. He suggests it's exactly because of the underlying narrative of each side.
I agree that all mainstream media, no matter if it's on the right, the left, center, government owned or not -- it's all full of bias to push the narrative each organization cares about.
Maybe 5% of the news reported is worth paying attention to, the rest may as well be garbage.
And often lacks nuance or historical context. I can't blame people for wanting to avoid complexity, that's why headlines exist, but there will always be information left out. Even from more honest reporting.
