OK, sure, but in the absence of affirmative action, are black high schoolers going into science and engineering programs at rates commensurate with their aptitude and interest compared with non-black high schoolers?
Obviously we're a bit off-topic from codes of conduct at the moment. But the specific claim I was responding to was that minorities and disadvantaged groups are not being excluded from CS today in the same way as they have been marginalized from society for millennia. You can draw a fairly straightforward line of causality from imperialism and slavery and Reconstruction and Jim Crow to, e.g., why fewer black kids in elementary school learned programming in the '90s via their parents' UNIX account from the local university and reading their parents' textbooks (which is how I originally got into CS as a child, and I've heard similar stories from several of my peers).
