If you agree with it, then it's fair. If you don't, then it's not. Pretty simple.
If they're on the Left they should admit it. Hate the Right? Admit it. On the Right? Admit it. Hate the Left? Admit it.
Talk radio hosts (Conservative) admit their bias and point of view up front.
Ironically, they do a much more thorough job of informing because they often explain the Left to make their points even though they admit to being on the opposite side of it.
Their audiences aren't upset with them and don't get mad at their admitted Right wing slants. They often engage Leftists who call in and try to challenge them.
It's not only good entertainment, it's wildly popular.
It's an information format the Left has yet to capitalize on because just like this forum, if you're FOS, you get exposed rather quickly by facts proving it.
The same reason Leftists on this board like you moe run away and refuse to debate facts or answer questions to counter your emotional outbursts.
I'd favor the MSM being subjected to same type of scrutiny through simple truth in labeling.
My prediction is their Leftist ideology laying bare and exposed for all to see without them hiding behind the farce of "objectivity" would spell their near immediate on air deaths.
I'd be OK with THAT!
