Nobody, even most liberal "journalists" think they're biased. Remember when someone asked Dan Rather where he thought the NYSlimes lay politically, and he answered middle of the road?
In short, most lib mediaites have no idea how perched they are on the left side of the abyss.
So why I think much of what comes out of Donald Trump's piehole is self-aggrandizing blather, he's right about the media. Much of what they print/broadcast is fake.
But again, their biggest sin is NOT printing/airing news not favorable to the leftist agenda. For instance, there are no lib scribblers/fraudcasters publicly wondering if the Smollett incident might be fake given the tremendous numbers of hoaxes in the news lately.
But, of course, they have an agenda to push...Evil Whitey constantly doing bad things to minorities, and stories like Smollett's help keep it going. Even after they're found to be hoaxes as Smollett's tale will almost surely turn out to be.
