Well by now, it should be abundantly clear that the OP was a farce to enter into an agenda. Call it pigmentocracy (sorry Sargon, it is a term increasingly being used by social scientists - Google it) or colorism, the suggestion is that "whiteness" is a privlege. To acknowledge white privlege is to acknowledge any light colored skin as a privlege within all races. Does it not having anything to do racism, since many cultures who embrace this may not have slavery, as it was mentioned, in their histories? Or does it, in fact, have to do with racism, and the desire by some to be white because that is viewed as preferable? Are there hierarchies within races, and is this racism? And nope, not blaming the victim as I am so lovingly always accused; I am asking an honest, soul searching question, especially of those without privlege.
If the OP was sincere, then this is a legitimate follow up. Otherwise, call it for what might be its true intent, to link white privlege to racism.
