I addressed that in the part of the post that you didn't respond to. What is and is not liberal and conservative is arguable as is whether most of the media is liberal or conservative. Either way, it doesn't matter if you want to find the truth of matters because you won't get the full truth flatout from either side.
That the OVERWHELMING majority of media is liberal is uncontestable - their bias is pervasive, constant, profound, decades-long, and deeply institutionalized. It's manifest in what they cover and don't cover, their use of the jargon of the left, the assumptions made in their news stories, how they manipulate video, who they pick to "represent" conservatives, on and on and on - they have a million and one ways to tweak the news.
During the 2008 election campaign, they gave up even the PRETENSE of being anything but obama cheerleaders - imagine how bad it is when even msnbc - MSNBC! - felt it had to yank Chris Matthews and Keith Olbermann from election coverage anchor jobs because of raw bias.
