Of course, they’re deliberately confusing two things, oppression and racism. The argument can be made that Whites were responsible for the former for some time and in many ways forced to atone by governmental actions, but racism has little to nothing to do with the former (and if anything, racism by Blacks is cancerous and has festered to epic proportions under the present regime, where they have not only lashed out at other races, but turned it on themselves, and the government, media and self-appointed leaders have utterly failed in its duties to address this poison, instead taking the usual route of continuing to “Blame Whitey” even though they have generally been out of the picture of directly causing Blacks problems for decades).
Noooooooo ... because racism is by historical understanding and modern doctrine a belief in white supremacy. ... I just mean to point out that this is the rejoinder that will be given. It's a purely rhetorical manouver, but that's what we're hearing.
Ironically, this is a result of the almost complete extinction of a belief in the doctrine of white supremacy. So, the insistence that blacks "can't be racist" is a last ditch effort to keep this doctrine alive, in effect.
It really is! That's what "white privlege" is all about, teaching whites that they are white supremacists, even though they can't even comprehend the notion.
