What’s eroding in Portland is the quality Max Weber considered essential to a functioning state: a monopoly on legitimate violence. As members of a largely anarchist movement, antifascists don’t want the government to stop white supremacists from gathering. They want to do so themselves, rendering the government impotent. With help from other left-wing activists, they’re already having some success at disrupting government. Demonstrators have interrupted so many city-council meetings that in February, the council met behind locked doors. In February and March, activists protesting police violence and the city’s investments in the Dakota Access Pipeline hounded Mayor Ted Wheeler so persistently at his home that he took refuge in a hotel. The fateful email to parade organizers warned, “The police cannot stop us from shutting down roads.”

All of this fuels the fears of Trump supporters, who suspect that liberal bastions are refusing to protect their right to free speech. Joey Gibson, a Trump supporter who organized the June 4 Portland rally, told me that his “biggest pet peeve is when mayors have police stand down … They don’t want conservatives to be coming together and speaking.” To provide security at the rally, Gibson brought in a far-right militia called the Oath Keepers. In late June, James Buchal, the chair of the Multnomah County Republican Party, announced that it too would use militia members for security, because “volunteers don’t feel safe on the streets of Portland.”
