Outside the minds of self affirmation/approval seeking pre-whatever students this issue is virtually nonexistent. There is so much silliness surrounding the word "doctor."
Legally I am an optometric physician. When someone asks what I do for a living, do I say I'm a doctor? No, that carries with it the connotation that I went to medical school and want to hear about the new growth on their foot. So I say I'm an optometrist, and then they tell me about their floaters instead. If they ask if an optometrist is a doctor, I say yes, for the eyes.
If you really want to, you could get into the weeds about whether an optometrist is a "doctor" in the same way a lawyer is a doctor. That answer is most accurately no, because unlike many other doctorate degrees, an optometrist prescribes a number of medications for medical conditions relating to the eye.
In the end, the whole debate is nonsense. My patients call me doctor, because that's my title. I treat them for eye problems, and they respect me for what I do. I couldn't give a god damn about another healthcare provider or anyone else taking issue with my title. We all have our jobs, and I consider myself pretty decent at mine. I don't mislead my patients, and I don't pretend to know things I don't know. I respect other healthcare providers who do their jobs as well.
Healthcare is broad, with many providers. Not all are doctors, and no doctor can treat everything, which I presume is why I have seen several patients who were prescribed topical antibiotics for uveitis from a non-eye doctor.
