Assuming racism is simply a matter of people not liking people of other races...which is a very feeble understanding of it. White people invented race in the first place largely to protect their privilege. First step in ending racism is to acknowledge this as well as the on-going privileges of whiteness. Singer never says anything about racists only being white anyway...and is simply arguing that violence against white supremacists at these rallies will not achieve anything productive. But it was not a white supremacist who was killed. Was it?
