I think it's useful to draw a distinction between racism and bias. Racism is real, but relatively rare - especially among people who have acquired sufficient societal navigation skills to rise to positions of power (whether in government, industry, academia, etc). Bias, on the other hand, is not only real but pervasive. It's unconscious but does affect the little decisions that every. single. one. of us makes every day - anyone who thinks he is free from bias has not thoughtfully considered the issue.
