pretending to be what you are not, to hide your intentions is the most important technology of biological survival. - Michiko Kakutani

The most appalling racist, sexist, and perversely cruel remarks are served up on social media, often with a wink or a sneer, and when called out, practitioners frequently respond that they were simply joking — much the way that White House aides say Trump is simply joking or misunderstood when he makes offensive remarks. At a November 2016 alt-right conference, the white supremacist Richard Spencer ended his speech, shouting, “Hail Trump! Hail our people! Hail victory!” When asked about the Nazi salutes that greeted his exclamation, Spencer replied that they were “clearly done in a spirit of irony and exuberance.

The assault on truth and reason that reached fever pitch during the first year of the Trump presidency had been incubating for years on the fringe right. Clinton haters... and Tea Party paranoids who claimed that environmentalists wanted to control the temperature of your home and the color of your cars... hooked up, during the 2016 campaign, with Breitbart bloggers and alt-right trolls. And with Trump's winning of the Republican nomination and the presidency, the extremist views of his most radical supporters—their racial and religious intolerance, their detestation of the government, and their embrace of conspiracy thinking and misinformation—went mainstream.

Trump often seems like a one-man set of Aesop-like fables — with easy-to-decipher morals like “those who lie down with dogs will get up with fleas” or “when someone tells you who he is, believe him” — but because he is president of the United States, his actions do not simply end in a tagline moral; rather, they ripple outward like a toxic tsunami, creating havoc in the lives of millions. Once he has left office, the damage he has done to American institutions and the country’s foreign policy will take years to repair. And to the degree that his election was a reflection of larger dynamics in society — from the growing partisanship in politics, to the profusion of fake stories on social media, to our isolation in filter bubbles — his departure from the scene will not restore truth to health and well-being, at least not right away.
