I think your teacher is overreacting. If you prefer a certain haircolor, are you a hairist? I find taller men to be more attractive, am I a heightist?
Unfortunately, this isn't a fight worth pursuing. The more you protest, the more people will think that you're in the wrong and start wondering about your values. Just take your punishment and move on.
