The current top of the executive branch made it clear that he equates black lives matter with white supremacists.
Miller and Bannon have gone ridiculously out of their way (and gotten thrown out in the courts over and over) to create explicitly racist policies.
They want to spend trillions to build an ineffectual wall to keep out the "other" - and you say that "the only institutional racism is affirmative action" ... that's what I would expect to hear from a white middle class person whose not experienced any hardship due to their race... ever?
