the following two responses work well.
1. for safety reasons, i do not discuss my personal security requirements with people i don’t live with.
2. immediately askcthe doctor how many weapons s/he has and how much ammo, and thenstart asking how many patients have they made iatrogenic mistakes on, and how many they’ve injured and killed over the years, how many lawsuits they’ve had, how much losses they’ve had to pay, etc. watch their reaction.
These doctors need to be reminded of the 200,000 people who die every year in America because of medical mistakes and incompetence.
