I see it this way.
We live in narcissistic culture of selfies, WWWF smackdown nights, reality-TV and other phenomena. I now feel alienated by the culture of my own country. I have a vague suspicion that this somehow explains why people are blind to Trump's vanity, lack of empathy, bullying behavior, indifference to the Truth, jealousy, vindictiveness . . . . and generally a low, amoral character incapable of either wisdom or real leadership.
The idea of a "liberal" media is a myth. Whether or not there are "liberal" journalists doesn't matter. Whether or not a media source follows the concept of "objective" journalism or "advocacy" journalism does matter.
FOX's owner had bought up media throughout the world. There are several FOX channels on the tube.
The reason CNN or MSNBC appear "liberal" to FOX adherents is that they adhere to objective journalism standards. In their opinion broadcasts, they will be seen as liberally biased because they argue a common sense deviating from crude, simplistic rightist ideology.
News events either happen randomly, or they are deliberately manufactured. Either way, events that can be cross-verified are reality. If news events are simply "made up" without the event behind them, they're simply crude black propaganda -- lies.
People on the Right seize on the "opinion" and "comment" portions of broadcasting as means of identifying a channel as "liberal" or "reliable." But it really boils down to whether an opinion exhibits logical inference, or ignores additional facts that change the result of logical inference, or is simply some shell-game produced to satisfy the chicken-little desires of an audience.
Righties believe that they are smart, they are individuals, they aren't average or average-of-the-mass, and therefore -- they can't be influenced as an average or average-of-the-mass. This explains their affinity for one source or one type of source which offers confirmation and amplifies their preferred sense of what is real. It is precisely the reason those sources can indeed influence them as a group or mass. The influence requires denial. The denial results from this heightened sense of self and a narcissistic culture.
And you'll never get them to accept this, no more than you could get Trump to admit his fallibility. They think that because they're "equal," their opinions must be the only ones that merit attention, and the opinions which correspond to the crude ideology are the only right opinions. Thus, in their imaginations, they assume that some plurality of news sources that follow objective journalistic standards must be some media conspiracy bent on robbing them of their rose-tinted view of what ought to be, as opposed to what is. They especially like to cherry-pick facts, throwing out those that don't support the belief system.
This provides a basis of group behavior such that group decisions can be group mistakes. And they will never admit to making collective mistakes. You could rub their nose in in the stark reality shit, and they still won't smell it.
