On one side I can say. Good for you kid for standing up to an establishment for your beliefs. However, don’t expect the change to happen just because you think it should. You are going to a conservative, religious school with centuries long standing of philosophy of ethics. Sometimes you have to take the ‘No’ and move on all this does now is put you in the light of strangers as a selfish teenager who sues because he didn’t get his way.
Reality sucks and not everyone will tolerate what you think is ok.
