Here is a remarkably thoughtful rebuttal to the remarks made by Sacha Baron Cohen in the video I posted previously.
One interesting quote:
Earlier this year, we discussed Yochai Benkler’s new book, the excellent Network Propaganda: Manipulation, Disinformation, and Radicalization in American Politics, which is filled with charts and data showing something pretty damn clearly: most of the disinformation and misinformation didn’t go very far until it was “validated” by a mainstream news source, namely: Fox News. Yes, the lies and shams did start out on social media, but they were mostly ignored. Until Fox News validated them, then they spread like wildfire.
