And it isn't hard to see the direct effects this is having, now. When the governor of Texas calls out the national guard to keep an eye on the US Army doing training exercises, because of right-wing conspiracy insanity that has hit the mainstream, we are having problems. When President Trump can claim that Obama is the founder of Isis and people just eat it up, we are having problems. For God's sake, the man had his press secretary go out on Day One of his presidency and lie about crowd sizes. He spouts bullshit about crime statistics in Sweden and for months, Breitbart suddenly has constant articles about how immigrants are causing everything wrong in Sweden ever (I particularly remember an article with an image of a mangled child, with the claim this was caused by immigrants, only for word to come out later it was a dog attack).
The "mainstream media" (and I use the term in quotes because all the biggest radio shows are right-wing, fox is the biggest cable channel and the WSJ is the biggest paper aside from USA Today) is like a dog chasing a car, towing a pro-business line and chasing after whatever will give them the most eyeballs at the moment. But at least they aren't a goddamn propaganda force for the left, marching in lock-step and feeding off each other the way the right media does.
