Simple solution when asked about firearms ownership,ask the doctor exactly what their technical training in the safe use of firearms is ,were its from Gunsite ,Blackwater some other training school ? If no such credentials ask the doctor if his malpractice insurance carrier knows what he is doing ?
A great diversion is to ask a question as an answer. When they ask about firearm ownership, ask them, “if I were ever to buy a gun, would it be best to get training on how to use one. Heck, you could have three full gun cabinets at home. It’s still a good rhetorical question. And besides, you could even continue to steer the conversation in the direction of a gun you are “thinking of getting”, causing him to naturally assume that if you ever did it would be your first gun.
This sort of thing is actually kind of fun. I’ve done it regarding other subjects.
