It is a group of newsmen supposedly bringing a harsh, critical light upon their own profession. When doctors say they want to run medicine without interference, liberals who run the media laugh out loud. They want bureaucrats in there, and lots of them. Media opinion never accepts that argument. Except in the case of one industry.
Media have a word for talk radio, which criticizes their liberal bias.
They call it Hate Radio. When Rush Limbaugh went on a media self-criticism show, they nearly had a heart attack. The problem with self-regulation of any industry is that it doesn't really happen. People in any business find it hard to believe that any of the people they work with would do anything really bad. They consider themselves all to be honorable people who are above that sort of thing.
