Angry presenters for angry people. It's a global disease. I'd recommend The Age of Anger by Pankaj Mishra. One of the most illuminating books I've read in the past couple of decades, it traces the genesis of today's populist/nationalist ideologies from the failure of the self-creating myth of the Enlightenment through (particularly) the Rousseau-inspired volk nationalism of Germanic peoples humiliated by Napoleon but also analogous movements in Italy, the U.K, and especially the among the hurt colonised peoples of the East..
As for mainstream outlets lending it legitimacy, you're right, but this isn't accidental. This is the thing about the Global Right: it's organised. It goes about systematically getting its message out there, its people into positions of influence, both in the media and in Government. About 600 think tanks, in every major country of the world are joined in a global network coordinated by the Institute of Economic Affairs in London - set up especially to confront environmentalism (and advocate for Big Oil, who still hugely funds them) but now also dedicated to fomenting the various rightwing agrarian revolts and right-wing populist movements in general. Inchoate anger, mythic culture totems and loathing of the educated: the standard cocktail of populist rage the world over, being stoked each and every day by paid sock puppets, media plants and downright propaganda channels.
