That was not his point. He was bashing Whoopie, not Jill Biden. His point was that Whoopie Goldberg thought that because Jill Biden had a Dr. in front of her name, she was qualified to become the Surgeon General.
Read his quote again
I love it when lefty celebrities demonstrate how fucking ignorant they are. Whoopie Goldberg said that Dr.Jill Biden is so brilliant that she should be appointed U.S. Surgeon General. Whoopie is so fucking dumb that she didn't know that Jill Biden was not even an M.D.
She cannot because she was/is not a M.D. (medical doctor) or a physician.
Education
In order to become the Surgeon General, an individual must first become a licensed physician.
