Meanwhile, one white supremacist and Ku Klux Klan leader, Chris Barker, said last month that his movement would destroy immigrants: “We killed 6 million Jews the last time. Eleven million is nothing.” As Paul Blest wrote in the Outline, “To pretend that the alt-right and Antifa are comparable is like equating the danger of playing Russian roulette with taking a walk.”

Nor can the two be compared in the political arena.

“They have no political allies,” national political reporter David Weigel of The Post observed of antifa, asking rhetorically, “Who is the Corey Stewart of antifa?” (Stewart is the Virginia politician who unfurled Confederate flags at rallies as he ran unsuccessfully in the recent Republican primary for governor and who says he will challenge Sen. Tim Kaine next year.)
