I had a french teacher call a girl a bitch when I was in school. He should have been fired but wasn’t. Teachers have no right to call kids anything other than young man young lady or by their name.

You are correct, teachers should not call students names. However, some exceptions remain. Coaches can call players what they want to (check it out, you'll find it to be universally true). And, students can call teachers whatever name they wish to call them, including bitch. You will never be able to force a public apology from the student.

That used to get students suspended, now it seems crude talk is the rage du jour, or something like that.
