I think this is specifically why medical doctors can refer to themselves as physicians. It makes no sense that medical doctors should suddenly own the title of doctor.I definitely know that PhD's are the original "Dr" (doctor in that sense meaning teacher). I was responding to the person who I quoted who said that physicians are not regarded as doctors, which is what my confusion was about.
But the function of that word has definitely changed, one definition being a "title" for PhD holders and the other definition being a "doctor", or person who practices medicine (in a general sense).
Which is why I think it is unreasonable for a person who has a PhD to say "I'm a doctor", rather than, "I hold a doctorate in...".
Plus, any educated person who could actually appreciate the hard work that was put into a person earning a doctoral degree of some sort would probably inquire as to what a Dr. is a doctor of.
I do take issue with some people holding the title of doctor, however. But, I think that's a different debate that will piss off a whole other group of people. 🙂
