From the article:
Last Saturday, self-proclaimed white nationalists carried torches through Charlottesville, Virginia, to invoke the racist legacy of Nazi Germany. Fire is more than a dramatic flare. In a charged context, it signals violence and destruction. The Nazi regime began by carrying torches at parades and rallies and, by 1938, burning buildings and Torah scrolls. It eventually burnt the bodies of millions of human beings. The very word Holocaust derives from the Greek, meaning sacrifice by fire.

In the 1920s and 30s, members of the Ku Klux Klan marched in torchlight parades, harnessing the theater of terror. White hoods and flame were their stagecraft.
