No, it's racism against everyone who is displaced from otherwise being admitted, so that the UC can under-the-table enact a policy designed to increase the number of black and Hispanic admits without saying it's affirmative action.
Well and classism against more affluent students displaced when some poor kid of any color at some rural school gets an advantage. Or favoring kids that are first to attend college is displacing kids with better-educated families.
I don't have a moral problem with this. It's not a good strategy in life to voluntary switch to a poorer performing school to give yourself a leg up in UC admissions while taking the cost of having less academically competitive high school classmates. It is a reasonable metric to view students through the lens of "how much have they accomplished given the opportunities afforded to them" -- the issue with something like Prop 16 is that it engages in statistical racial discrimination (mostly against racial minorities for that matter) to make that consideration.
