First of all doctors (or, in their tadpole-form: medical students ;-) ) should be welcome to have whatever political opinion they choose, not be funneled or channeled into some predilection of a particular power-elite du jour; nor by similar justifications be given preferential (ab initio) medical school admission.
Medical school should be about teaching medicine, and the techniques and science behind it. If and when there are strong compelling political arguments of the day (i.e. always), let's not presume patients are ignorant, and let's not presume patients, when they are having (say) their diabetes treated need to hear our political points of view. Certainly if they ask, we are welcome to supply our own opinions but emphasizing that it is merely just that: our own opinions.
When someday you or I get old (you first please), and need a cataract removed. I hope that the doctor with laser or blade in hand got to that position directly above the waiting eyeball not because of affirmative action, social justice, political opinion, or anything but competence, knowledge, and expertise.
Ironically, just earlier today, I was reading a great post by Thomas Sowell: Using words to confuse , wherein he touches on the concept that "social justice" may be neither very socially redeeming, nor very just.
Warm, fuzzy words and phrases have an enormous advantage in politics. None has had such a long run of political success as "social justice." The idea cannot be refuted because it has no specific meaning. Fighting it would be like trying to punch the fog. No wonder "social justice" has been such a political success for more than a century... There is a strong sense that it is simply not right – that it is unjust – that some people are so much better off than others.... Is the person who has spent years in school goofing off, acting up or fighting – squandering ...dollars ...spent on his education – supposed to end up with his income aligned with that of the person who spent those same years studying to acquire knowledge and skills that would later be valuable to himself and to society at large?
