For the second time this year, millions of people have taken to the streets of cities and towns across the United States in response to the authoritarian tendencies and tactics of the second Trump administration.

These crowds gathered under the “No Kings” banner to register their deep disapproval of: immigration raids and deportations without due process; the deployment of National Guard troops to cities against the wishes of elected officials; the use of legal threats, intimidation and extortion against the administration’s critics and non-sympathetic institutions; the selective prosecution of Trump’s political opponents and protection of his supporters; the closure of federal departments and mass sackings of federal workers; harsh proposed budget cuts that will disproportionately affect the poorest Americans and their ability to afford health care; and overt forms of corruption undertaken to enrich the president, his family and allies.

It is undeniably heartening to see citizens join with their neighbours to express a shared commitment to certain democratic values in the face of the relentlessness and brazenness of an administration that treats those values with contempt.

And yet Trump’s second coming has brought with it something else — certainly present in the first administration, yet, like so much else, exaggerated and emboldened this time around. There is a manifest indecency, a crassness, a cruelty and delight in the humiliation of others, a contemptuousness and a preparedness to sacrifice basic forms of democratic morality on the altar of political partisanism. Leave aside the rhetoric used by senior administration officials in the aftermath of the assassination of Charlie Kirk, or the grotesque flirtations with Nazi symbols and racist tropes by GOP staffers.

In response to the “No Kings” demonstrations, President Trump posted an AI generated video of himself piloting a jet labelled “King Trump”, which he flies over protesters and dumps what appears to be excrement over them. The White House proceeded to post an AI generated image of President Trump and Vice President Vance on thrones, wearing crowns, over an image of Democratic leaders in the House and Senate wearing sombreros.

Partisan politics, it seems, becomes licence to disregard the fundamental moral constraints on conduct toward our fellow human beings, to say nothing of members of the same political community. As George Packer puts it, “Once morality is rotted out by partisan relativism, the floor gives way and the fall into nihilism is swift.”

And yet for someone like John Dewey, the cultivation of everyday democratic virtues like decency, mutual consideration, turn-taking, forbearance and gentleness in our speech — as well as, negatively, the refusal to call each other names or to form ourselves into cliques and castes — is the way “democracy becomes a moral reality”.

So while protesters gather on the streets to take a stand against such an obvious assault against the edifice of American democracy, it could well be that there is a more insidious threat working its way through the soul of the nation — as well as those of advanced democracies like Australia, France and the UK — in the form of the disregard for democratic decency itself. Dewey didn’t think a democracy could survive without this moral glue. Do we really want to find out if he was right?
