The media have done this all by themselves. I know you like to patronize us to make yourself feel so sophisticated, but I read the WashPost every day. It's no longer a newspaper in he traditional sense of providing factual news. It is all about advancing various leftwing agendas, eg Trump hate, war with Russia, AGW, every conceivable LGBQXYZwhatever, racial divisiveness open borders, etc.
The mainstream media have been biased all my life. There are two major differences now. One, we have alternate sources, which the mainstream media bitterly resent. They view their role as setting the agenda, deciding what is newsworthy and what is not. They have lost much of that power and they are furious about that, so they attack the alternative media and try to discredit them.
Two, the media are not at all concerned with the truth. It is all about winning, specifically beating Trump. They hate Trump more than they did Richard Nixon. They will do and say anything to beat him.
The NYTimes isowned by the richest man in mexico, Carlos Slim. The WashPo is owned by billionaire Jeff Bezos, whose amazon business is largely based on selling cheap crap from china. No conflicts there. The TV and cable nets are run by a group of men who are, shall we say, not very religiously diverse. Unsurprisingly, they all, even Fox News, advance a narrative that is at odds with the way most of the country see things. But is all due to Russian interference no doubt.
