There is always the Henry Kissinger line about Iraq and Iran in the 1980s "Can't we hope for them both to lose?" But Barro has an important point about the deterioration of journalism culture and social media culture, which is the public culture of the newest adult generation and likely to have some influence for fifty years.
Airing internal workplace disputes in public like this is not okay, even when you are right on the merits. My statement isn’t just obvious, it’s how almost all organizations work. If you think your coworker sucks, you don’t tweet about it. That’s unprofessional. If you disagree with management’s personnel decisions, you don’t decry them to the public. That’s insubordinate. Organizations full of people who are publicly at each other’s throats can’t be effective. Your workplace is not Fleetwood Mac.
I reflect on my hospital career. One could say many bad things about the hospital to one's family, or one's Bible study, or the fathers you were talking to at Cub Scouts or soccer games or whatever. But you didn't put it in print in any way. I got in trouble for an anonymous parody of hospital decisions in the 1990s, which I put up on a pillar in the lobby, but got picked up by the Concord Monitor. Front page, gulp. It was really funny, though. I just had to let you know that part. If you wrote a Letter to the Editor about the hospital, you worded it carefully, and even then worried about blowback. Or at least, so I'm told. Never went their myself. Even now I only refer to management decisions, especially personnel and discipline, very obliquely. I don't know everything behind those decisions. I don't like to find out that I said something stupid a month later.
