Who will resist the jackbooted terrorists that want to take over America?
Racism is systemic oppression of minority populations based on the idea that the dominant group in society is superior. In the case of western civilization, white culture has been dominant. Our entire civilization has been founded on the premise of imperialist white supremacy. Despite what one might read on a bunch of Alt-Right blogs, white people in America are not the victims of racial oppression. You must be part of the dominant group to racially oppress someone.
