There is as much to be gained going to bat for 'cracker' as there is in any argument over bigotry being symmetrically applicable to both the oppressor and the oppressed. In a framework of white supremacism, which has been imposed onto the world by western cultural hegemony, all peoples are to be racially denigrated in favor of the "white race." This can be done by white or non-white people, but it can only be done to non-white people. One can be prejudiced against white people and can call them names, and that is a direct result of this system of racism, but it isn't a part of it

This concept is important for understanding any dynamic of oppression. Anti-white racism isn't possible because it's predicted on 'white' being anything other than the identity construct created solely to "be supreme." Misandry isn't possible under patriarchy because its concept of manhood is the same type of construct. Classist bigotry can not be applied against the ruling class for the same reason, 'cissie' can not be a slur, and so on
