no one is denying it. however, the understanding of what race and racism are have changed and wer'e tyring to argue two things:
1. any ruling elite (whether racial or whatever) are not and do not act as a homogenous entity completely without contradictions, gaps, fissures. there is ample historical evidence that racism and racialization is a process and that it needs to be analyzed that way.
2. that "whiteness" has a history. that you need to look at both the "racialized" targeted group and the "whites" in order to fully grasp how that history unfolded and how it manifests itself today.
