A former primary care physician asked me if I had guns in my home. I declined to answer. They then delivered a little speech about gun safety and children. I then mentioned that I don't have any kids. That shut them right down.
I have not faced that questiong, yet. Good answer though albeit I think just responding “it is non of yours or the governments business.” is the proper answer. Remember, when they start inputing all that health related info into national data bases. This is setting the plate for the Stassi to come seize your guns for your own safety and that of “the Children”.
I changed OBs when mine asked me about guns, I said yes, he mentioned the danger of guns. I said it was very good rape prevention, and as an OB, that was a far greater danger for a college aged female living where she could afford to live (not great place, but could save up money).
I had a defective bullet jam my revolver. While trying to clear it 15 minutes later, it fired (downrange) I burned my hand pretty badly so I went to my doctor. He just laughed. I really appreciated that. We joked about it every other time I went to see him.
