Never say -any- MD. There are a lot of MDs out there fighting to change the world in a lot of ways- from pioneering and promoting new newborn screening protocls/requirements, to going to botswana and giving their services free.
Moreover, your doctor spent something like half a million dollars and many years of their lives to learn the profession you're paying to see them for. They went through hell in residency and put their families aside.
If you don't want to respect your doctor, get a new one.
Yes, there are some asshole docs- I've had one or two or three, there are some who are very caring but have the bedside manner of a turnip, and there are some who will melt your heart.
But remember, they worked hard to get there, you're paying them to be professionals, treat them like professionals.
