Authoritarianism is bad, but it is bad in much worse ways than racism. Most cultures, let's face it, has some racism. Even the most divine society, would be racist against an alien race. It just doesn't show its ugly face, most of the time.

The outrage is really about mandated bad teaching environments. There are also very bad side effects for minorities, but calling it racist, when the culture is overall about domination, is missing the target.
