I agree that it’s quite likely racism is the problem in this instance. My point is that schools should under no circumstances be telling students how they need to wear their hair; apparently this school has a dress code that stipulates hear length. Schools exist to give students the knowledge they need to be successful once they reach the age of 18. They should not be policing how the students groom themselves or dress; that should be up to the parents. There should not be a “dress code” in the first place, outside of “don’t show up to school naked.”
