You are holding her to the standards of an adult American; she is neither, and never had any business even being in the school (it is a state school, and not easy for white/Asian males to enter). One good thing is that when I was in a state school years ago here in NJ, you stop seeing these people in serious classes by sophomore year; they fall out of the real classes and take fake classes instead.
This thing already graduated, but still had plenty of time to come back for “victim rallies”; I’m sure she is unemployable. Her resume is tailored for a meaningless state job (pushing the preferred minority status).
