Commenter Buzz Mohawk notes:

To me the pseudo-science of systemic racism resembles a tautology, one that hangs together with the pseudo-legal concept of disparate impact, thus:

Where (you think) there is disparate impact, there is systemic racism. Where (you think) there is systemic racism, there is disparate impact.

All of this is made possible by the tabula rasa postulate, which states that all humans are equivalent blank slates.

In other words, all differences in human outcomes can be explained by racism.

Couple this with the fact that schools are now teaching two additional postulates, 1) All white people are racists, and 2) Nobody else is, and then you arrive at the corollary: Everything is white people’s fault.

Thus the conclusion: All failures of everyone else to achieve as much as white people are disparate impacts caused by systemic racism.

It’s all one big circle jerk.
