I said ordered by significance. If something is left out of my ideally objective news outlet, then it was, by construction, less significant than the things that were included.
To address your second point, connotation is objectively a part of meaning. I did not merely require that this ideally objective news source SEEM objective. It has to actually be objective.
Frankly, the argument you made was that the existence of "farther right wing" media pushed fox towards the center.
All I have to do is demonstrate that there exists an objective presentation of newsworthy facts, even if only in an abstract sense, and then show that fox has not changed its position relative to itself, over time, to show that your argument is false.
Centered does not mean average, when it comes to reporting, it means objective.
