Simple solution. Find a new doctor. If you have to, move. Yes, my doctor knows I own guns, a lot of guns. So does the State Police and the county Sheriff (also a good friend). As to the doctor, one of the nurses there is also a shooter, and I'm supposed to teach her reloading eventually. She left, but we'll find her.
Point is, there are fixes to these problems, and yes, most medical professionals are very liberal. But, not all are. Some are very conservative, many are neutral.
