Well, the doctor is intelligent, beyond his medical training, in my opinion. His situation is not unique, except for his insight into his need to cope with possible negative stereotypes he has to live with. Meaning, many ethnics/minorities do need to give a little extra, in the way of care/concern, when dealing with the majority group. Otherwise, while the response might not be "uppity," as in the article, but possibly "arrogant," "superior," "perfunctory," or some other pejorative thought to assign negative sterotypical behavior.
Anyway, I do not think the need to tread on eggshells, so to speak, will end anytime soon, unless one thinks two or three thousand years is a short time.
An anecdotal story of why Jewish doctors might be considered good, for curing one's ills, comes to mind. Jewish students historically needed an A+ college record to get into a medical school, in the U.S. The Christian student could get admittance with a lower average. So, today there are those that believe that a Jewish doctor is just "better." Perhaps, a Baptism in fire does make for stronger person?
Getting back on topic, the Black doctor giving a more concerned effort to his patients is just the better way, and if most Black doctors follow suit, then many a patient will specify they want to see the doctor (that is Black).
For example, here in NYC West Indian nurses from the West Indies are often considered more caring to infants (for mothers that had a CS, and need help at home initially) by many a white mother, I believe. In my opinion, this is possibly due to their realizing that they need to be "selling" something that a white nurse may not have the inclination to sell (a more demonstrative tender loving care to the infant?).
I believe, the focus of this article should not be a lament that the doctor needs to go 55 mph in his life, but that everyone else might consider it beneath them to go 55 mph in life, and 55 mph is the ojectively correct speed to go in one' life.
Digressing a moment, didn't Satchel Paige once say he never runs for anything? (I know I'm using a double entendre.)
