If there is a problem with the media in general (apart from strong political bias), it's a human problem that we all share. People respond to shock, outrage, and disgust much more than they respond to pragmatic ideas, logic, or even truth in general. As long as media companies are built on revenue models tied to ad impressions and social engagement, we'll likely see more of the same.
Censorship will not help; it can only make the problem worse. Perhaps instead, social networks should return to being social networks rather than scrolling billboards. I recall a time (around 2005-2006) when Facebook consisted mostly of people's own words, thoughts, and conversations rather than embedded media. I think I'd really enjoy a Facebook that didn't even turn URLs into hyperlinks - one where the only media that can be embedded is your own original content. That's partly why I believe Instagram is on the rise, while Facebook seems to be on the decline (depending on who you ask - and yes, I know Instagram is owned by FB).
The current social media landscape is like trying to host a party at your house with TVs on every wall (showing random propaganda) so loud that no one can even hear themselves talk.
