You know - that tedious, slow, boring, and often costly activity which proper journalists are supposed to undertake before publication.
The reputable polar opposites are Fox News and MSNBC with everyone else somewhere in the middle. You can legitimately tell that someone listens to conservative media if they consider CNN left wing.
This is the general problem. You've got good, honest people who already have biases and the echo chamber is so loud if you're not vociferously fighting side X you're obviously side Y.
I highly agree that most news nowadays has become clickbait focused in an effort to both drive revenue and stir up loyalty by making people pick sides.

CNN is left leaning but that is not the source of my gripe with them. I don't like the "hair is on fire" 24/7 style reporting they do, and I find that their quality work gets lost in a mess of exactly that kind of "everything is fucked and we're all going to die" style of reporting.
There are plenty of what people would call left leaning orgs out there that do excellent work. CNN is not among them IMHO.
