I think this could be driven by personalization of internet content. It started with the innocuous idea of presenting only the information you need. And, it turned into a system of echo chambers where your world view would be limited to certain ideas that you are comfortable with. And, it leads to lots of cognitive distortions. Also, the abundance of media on the internet force the content of the media to be louder for it to be visible. Nuance has to give way to crass generalization to get deeper media engagement.
I seriously worry about the trend and I am not very hopeful about the direction it takes.
