I absolutely agree that our current situation needs to be improved, but looking at the history of media leads me to believe that by progressing past the centralized and regulated system of TV and radio we've left a local maximum when it comes to "civility". Older forms of "ugly" news, like the press of the french revolution or turn-of-the-century america, didn't get fixed over time, but by the law "catching up", either through oppression or the increase of regulation causing regulatory capture. Of course, the idea of recentralizing speech is more or less unacceptable: what would that even mean when the problem is not a small group of newsmakers, but literally everybody? I don't see any other solutions in our long past, though.
