Unfortunately there is def racism, political bias and other forms of discrimination in medicine. I remember having emergency major surgery and the doctor only giving me Tylenol when I've seen him give painkillers to white patients essentially for stubbed toes. I think he got sued or something because the place eventually went out of business and they ultimately threw my bill out.
This woman should lose her medical license. A doctor is supposed to act in the patients best interest period regardless of perceived beliefs.
