Only people with Ph.D.'s in hard sciences and medical doctors should be called "doctor." This has been my consistent position for over a decade, as the execrable @michaeljknowles can attest.

I speak as a "Juris Doctor." No lawyer should be called doctor. It's idiotic. In law school, one of the students had a doctorate in a liberal art. When the professor addressed the student but forgot the honorific, another student piped up, and said, "You should say 'Doctor.'"

The professor quickly replied, "If I have a heart attack right now, can you do anything about it?" The student demurred. The professor replied, "Then I'm not calling you doctor." This is basically my perspective on this asinine issue.

If you're at a dinner and somebody introduces himself as "Dr. Smith," you'd be rather upset to learn that he had a doctorate in musicology if you were to suffer a stroke at the table.

Furthermore, to compare a doctorate in education (or law, for that matter) to a medical degree is the height of absurdity. Having watched my wife do the latter, it simply isn't comparable.
