Sorry for the thread hijack, but since I didn't start it, and you fed us:
Here's what's funny. She works for you. Your tuition pays her salary. She has bosses. There is a dean of students who is supposed to be there to represent the staff to the students should an issue arise. Public school teachers work for the taxpayers whose children they are educating. Write it up like it should be. Then when she grades you down, you take it to the dean of students, or the chair of the department, or the dean of the entire school and fight it. That's the only way things like this can change, if people stop taking the PC entitlement BS laying down.
