Yes, I was asked about gun ownership by a doctor in New Mexico in 1999.
This happened to me in the same location in 1988, when I took my 4-yr.-old son into an emergency room for a couple of stitches on his brow over the bridge of his nose after he rammed it into a sharp corner of a piece of furniture while tearing around the house like a Boston Bulldog on speed.
I told the physician it was none of his business, left with my son, and patched him up with superglue and a butterfly bandage (repeated often, after that incident).
Physicians are complicit in instituting the nanny state, and should be scorned and spurned at every opportunity.
