Whatever else Trumpism may be, it is the systematic organization of resentment against outgroups. Trump’s record is rich in dehumanization. It was evident when he called Mexican migrants “criminals” and “rapists.” When he claimed legal mistreatment from a judge because “he’s a Mexican.” (Judge Gonzalo P. Curiel was born in Indiana.) When he proposed a “total and complete shutdown of Muslims entering the United States.” When he attacked Muslim Gold Star parents. When he sidestepped opportunities to criticize former Ku Klux Klan leader David Duke. When he referred to “very fine people” among the white-supremacist protesters in Charlottesville. When he expressed a preference for Norwegian immigrants above those from nonwhite “shithole countries.”

This is more than a disturbing pattern; it is an organizing political principle. And it has resulted in a series of radiating consequences.

First, it has given permission for the public expression of shameful sentiments. People such as Blankenship, Williams, Arpaio and Nehlen are part of a relatively (and thankfully) small political group. But the president has set boundaries of political discourse that include them and encourage them. Even when Trump opposes their candidacies, he has enabled the bolder, more confident expression of their bigotry. The Trump era is a renaissance of half-witted intolerance. Trump’s Christian supporters in particular must be so proud.
