Rich Lowry writes at National Review Online about major journalistic failures within mass media outlets.

The American media — long stalwart defenders of the First Amendment — are now having second thoughts.

For decades, it was a commonplace sentiment among journalists that freedom of the press was one of the glories of our system. It helped to make the government accountable and to air diverse points of view — even unpopular ones — to be tested in the marketplace of ideas.

Media organizations were at the forefront of the fight to vindicate First Amendment rights, with the New York Times involved in two landmark Supreme Court decisions (New York Times Co. v. Sullivan and the Pentagon Papers case), and tended to rise as one against any perceived threat to their prerogatives and freedoms.

This advocacy has been sincere, although, if nothing else, journalists should be First Amendment purists out of a sense of self-interest. In a 2018 essay in The Atlantic representing the bygone conventional wisdom, titled “Why a Free Press Matters,” the longtime newscaster Dan Rather noted, “As a working journalist, I know I have a stake in this concept.”

One would think so.

Yet now journalists have lurched from finding a threat to freedom of the press in every criticism of reporters and news outlets by former President Donald Trump to themselves calling for unwelcome media organizations to be shut down.

They’ve become the thing they profess to hate — closed-minded censors who want to stifle free expression, First Amendment be damned.

Perversely, the TV program and email newsletter of the top media analyst at CNN, Brian Stelter, have been clearinghouses for such advocacy, whether it is demands to get right-wingers removed from social media or — more astonishingly — to keep conservative cable networks off the airwaves. …

… All of this would be bad enough if it weren’t people who write and comment on TV for a living advocating it. But journalists have been moving in this direction for a while now
