Um... Worrying about WWIII and the world dying in a nuclear conflagration goes a bit, make that WAAAAAY beyond, the concerns of just 1960s atheist hippies.
Now we have right wingers screaming about the "radical right," allying with hard-line Communists on the Donetsk and Luhansk "people's republics," and praising Joseph Stalin as the savior of Europe from the Nazis.
Um... Communists in that region of the world are largely gone. More Communists probably exist in Berkeley.
Anti-Fa started in 1930’s Germany as a communist terrorist group.
Somethings never change.
