What? Not blaming any victims, but pointing out that those human beings enslaved years ago in the continent of Africa were enslaved by people of their own race. Slave Traders and Slave Owners saw these human beings as disposable economic units to be exploited and replaced. The same could be said of those Slave Dealers who supplied them. Differences in skin colour seem less important than similarity of attitude. Concepts of racial inferiority are normally related to later justifications based on some peoples' use of early work on genetics. I do prefer to be consistent, and would no more "blame" the ancestors of many black people in America for being enslaved than I would "blame" the ancestors of many white people in Australia for their having been transported. It's the Power Relationships that matter, though I appreciate that a derisory parrotting of "Blame the victim!" is convenient, and certainly more attuned to the spirit of the age.
