Legally, I can call myself king of the universe if I want to. That doesn't mean people won't laugh at me for doing so.I do believe the issue went before some ethics advisory board who OKed it as long as there wasn't an appearance you were calling yourself a medical doctor.
Additional question. I am teaching a college political science class this fall. How douchey, on a scale of one to ten, would it be to ask them to call me Doctor?I don't really want the freshmen to call me by my first name, and "Mr _____" seems odd to me. Perhaps i'll go with "professor."
In my view, I would say that yes attorneys can, but they generally don't because the law profession has its own terminal degree.
