The neo-Nazis and white supremacists who marched and brawled in Charlottesville, Virginia, this weekend wore their whiteness like a shield. It was proudly evident in their uncovered faces and their arms outstretched in Hitler salutes. It was displayed on their bare skin, which flaunted tattoos of swastikas and Confederate flags.

Mark Peterson’s photographs capture the baleful scene, illuminating the protesters’ faces and eyes, some of which are joyful in their hate. They bludgeon and stamp on counter-protesters, who scramble and care for the fallen, including Heather Heyer, struck and killed by a white supremacist’s car.

Their assailants had no need for hoods and masks, not when they have a defender in the White House. In these photos, they are naked and unafraid. The faces of the white supremacist leaders Richard Spencer and Jason Kessler are eerily pale, almost incandescent. But the face of David Duke, a former grand wizard of the Ku Klux Klan, is partly cast in shadow, as if gesturing at the deep darkness from which this virulent brand of American hatred springs.
