Beyond Greenwald being highly cogent as usual, the BBC interviewer demonstrates the propagandistic bent of most media presenters. The essential skill of these presenters lies in distorting information in real time, to serve to an implied structure of authority.
Propaganda is natural to the human mentality. It’s not, then, that media presenters and organizations are doing something no one else does. Rather, they have made a practice of doing what everyone else does unconsciously. They doggedly raise bias to a professional level, even though this directly violates their supposed Prime Directive.
Greenwald, by contrast, is one of those few who actually takes the premises of journalism seriously. Those premises include a concern for factual accuracy, and a notion of the public good intimately connected with the idea of that, within a democratic society, the general public has a right to know.
The supposedly serious news industry gave birth to all the crude forms of fake news by abandoning these standards, whether in service to profits or to power.
