This was the old problem. It was solved by having groups of experts and journalists. This wasn't popular because one group of people kept Having their feelings and biases attacked. They were later served by the media empires built to serve their views. They got their experts and their talking heads to say things they felt needed to be said. In so doing the first false dichotomy was established - feelings and opinions are the same no matter the facts and the experts disagree. So the first layer of agreement/expert concord was breached. This results in the problem you describe. What we face now is fiction being camouflaged as news sites, and super insulation/echo chambers. This is happening at the margins. Topics and people which are capable of being attacked in this manner. Later the surface are of attack will increase as technology, technique improve while human fatigue sets in.
