I think that's all well and good with opinion/editorial content. I think where you get into trouble is when "news" personas start pushing factually inaccurate stories as if they are true. I'd love to say it's just Alex Jones and his "Sandy Hook was a hoax" stuff, but even Fox has fallen down pretty badly in this respect, going as far as being sued by Seth Rich's family for running their - disproven - story that he was murdered for leaking internal emails to Wikileaks and that it wasn't Russian hackers, and even after Fox redacted it, Hannity continued to stand behind the story. Shit like that crosses a line from editorial content and arguing interpretations, to trying to get the viewing public to believe falsehoods for political gain. The former is necessary for a healthy democracy, the latter is extremely destructive to it. I'm with Randy, some sort of return of the Fairness Doctrine would go a long way here, though it would take some work to figure out how to apply it to social media.
