Clearly, you never spend any social time with MD’s and hear about their patients if you think this isn’t a problem in medicine. I really think if Dr.J never again has to hear the phrases, “Now, I’m not telling you how to do your job,” or “Now, I know my body, and…” he will be able to die a happy man.
That’s really neither here nor there, though, as I don’t think that’s at all the reason we should use honorifics in formal, professional settings. We use honorifics because that is (or at least used to be) the default setting for professional settings. That’s why my mom’s coworkers call her Mrs. CatLady in front of students, parents, and in staff meetings, although they typically call her Paula when they’re just shooting the shit. That’s why everyone in our clinic uses honorifics for our clients unless they’re people we already know personally or they tell us otherwise. That’s why my bosses might use a nickname for me in the treatment area, but always call me by my real name in the exam room. That’s why when I took EMT training they taught us to always, always, always call the patient by an honorific (yes, Mr., Mrs., Miss, and Ms. count as honorifics) and last name until told by the patient to do otherwise. That’s why we call judges Your Honor and sometimes call lawyers Counselor. That’s why people address the Commander in Chimp as Mr. President instead of just calling him George.
That’s not to say that the level of formality can’t be reduced in a professional setting. I’ve yet to see a mechanic introduce himself to me as Mr. Gearhead, but rather by first name. We don’t address them by honorifics because they tacitly tell us not to.
But your focus on the medical profession, coupled with your comments about MD’s you’ve worked with and how they irk you, really does make it come across as though you’re not lobbying to drop all honorifics, just Dr. And that makes it come across as an issue that’s a little more personal than you let on.
