Edit: getting a lot of down votes but not a lot of discussion below. This isn't just a "whatever maaaaaan I'm not a part of this system" post. It's also not a thinly veiled attempt to push a political view. I really am talking about objectivity.
For example, even among publications that share my general bias, it is easy to identify that they are omitting information that could be relevant in the name of cohesion and persuasion.
I am not willing to ascribe a certain motive for it because there is truthfully a lot of potential motivations. But that doesn't change the fact that the bias exists, and we cannot call it objective as a result.
