What the hell are you talking about? It's a left-wing propaganda channel, IMO, which is nonetheless seen as a lot more trustworthy than Fox "News". How can my personal opinion be compared to a poll of many other people?
The larger point, which you are ignoring, is that the general assessment of the "mainstream media" as being "left-wing" by the right is because pretty much everyone on the right thinks their insular right-wing sources are the only ones that can be trusted -- and nobody else agrees.
Every time I turn on Sean Hannity he whines about "media bias" -- and then spends three hours on right-wing ranting. No intelligent person can take him seriously, nor his online equivalents like the right-wing mouthbreathers in this forum.
