Isn't this a perfect example of "liberal media" bias?

The media has a role to play. It is supposed to report the new and the facts of events. The problem is, the medis is made up fo human beings. By nature, humans have ideas and opinions. For whatever reason, the medis seems to be predominatly liberal in nature. Therefore you have a liberal bias in the media. It is what it is. Just recognize it for what it is and learn to do your own research, as most medis types, although they may know both sides of a story, tend to tell the one that agrees with their ideas.
