It’s not racism, it’s simply beating up the smart students who are ruining the grade curve.
My district has a very large Asian population. There used to be brawls in the hallways of the high school because white kids were upset that the Asians were getting all the good grades, scholarships, prizes, etc. Eventually, it all calmed down and now the high school is supposed to be one of the best in the country. The Asian kids were the ones who raised the bar — not the teachers or the administrators.
