The first time a doctor asks me a question like that, they just as well start preparing a copy of my medical records to forward to my new doctor.
Don't be too hasty. The first time I ran across questions about guns at a doctor's office, the doctor had American Rifleman magazines in his waiting room. His insurer insisted he use the forms with the questions on it. He did not have to require patients to answer the questions about guns.
Do you have kids digger?
Most if not all urban pediatricians ask that and other intrusive crap on their forms as a new patient
Just like hospitals always ask if anyone has abused or threatened you in your home our workplace
I know its for women mostly but they ask me too
So silly
Instead simply ask the Doctor Sir exactly what formal training in firearms safety have you had & does your malpractice insurance carrier know you are asking these questions & would you like me to inform them .
The threat of calling the malpractice insurance carrier & telling them about the Doctor practicing outside their scope of practice will have a sobering effect on all but the dimmest in the profession.
