Just because they are further to left than the general media, doesn't make mainstream media not biased towards the left and thus generally liberal.
It seems that most people here are not seeing the bias n the media, since it thir bias also, so they are seeing the media as they want to.
Except, again, if you aren't familiar with the work of Chomsky & Herman then you're sort of blind to the assumptions you're making. Maybe you have a different definition of 'left' than is generally accepted
