Michelle Goldberg points out in her Times column that what we have here is not a crisis of civility but a crisis of democracy.

[T]here’s a moral and psychic cost to participating in the fiction that people who work for Trump are in any sense public servants. I don’t blame staff members at the Virginia restaurant, the Red Hen, for not wanting to help Sanders unwind after a hard week of lying to the public about mass child abuse. Particularly when Sanders’s own administration is fighting to let private businesses discriminate against gay people, who, unlike mendacious press secretaries, are a protected class under many civil rights laws.

That “not wanting to help Sanders unwind” is good.

Whether or not you think public shaming should be happening, it’s important to understand why it’s happening. It’s less a result of a breakdown in civility than a breakdown of democracy. Though it’s tiresome to repeat it, Donald Trump eked out his minority victory with help from a hostile foreign power. He has ruled exclusively for his vengeful supporters, who love the way he terrifies, outrages and humiliates their fellow citizens. Trump installed the right-wing Neil Gorsuch in the Supreme Court seat that Republicans stole from Barack Obama. Gorsuch, in turn, has been the fifth vote in decisions on voter roll purges and, on Monday, racial gerrymandering that will further entrench minority rule.

Minority, white, reactionary rule. Gorsuch is the crucial 5th vote that makes it possible for Republicans to steal elections – to continue to win despite losing the popular vote – far into the future.

[M]illions and millions of Americans watch helplessly as the president cages children, dehumanizes immigrants, spurns other democracies, guts health care protections, uses his office to enrich himself and turns public life into a deranged phantasmagoria with his incontinent flood of lies. The civility police might point out that many conservatives hated Obama just as much, but that only demonstrates the limits of content-neutral analysis. The right’s revulsion against a black president targeted by birther conspiracy theories is not the same as the left’s revulsion against a racist president who spread birther conspiracy theories.

Faced with the unceasing cruelty and degradation of the Trump presidency, liberals have not taken to marching around in public with assault weapons and threatening civil war. I know of no left-wing publication that has followed the example of the right-wing Federalist and run quasi-pornographic fantasies about murdering political enemies. (“Close your eyes and imagine holding someone’s scalp in your hands,” began a recent Federalist article.) Unlike Trump, no Democratic politician I’m aware of has urged his or her followers to beat up opposing demonstrators.

Instead, some progressive celebrities have said some bad words, and some people have treated administration officials with the sort of public opprobrium due members of any other white nationalist organization. Liberals are using their cultural power against the right because it’s the only power they have left, and people have a desperate need to say, and to hear others say, that what is happening in this country is intolerable.

It’s all we have. They’ve stolen or shut down the more official avenues of dissent and resistance, so unofficial is all there is.
