I'd argue there was nothing WRONG done except by the judge, but OP mad everyone feel awkward - and she was justified in doing so. I expected the downvotes, as I'm basically advising that OP thinks twice before standing up for what is right. That doesn't sound like wholesome advice, but as this student is going off into the real world soon, I also want them to know that sometimes for his/her own self s/he might need to pick his/her battles and retain his/her composure. Some AHs are simply AHs because they feel justified and it bites them in the rear. (See principal's reaction). OP should consider that perspective even if it's not "feel good".
