Anti-female attitude=bad; anti-bozo attitude=good!
Still not clear if the guy had your wife's express permission to pick up her piece and uh, do nasty things to it.
A friend used to own one of those little 22short Beretta autoloaders, and unwisely left it out during a party at his house. (Yes,I know, etc etc)
It seems that a "guest of a guest" saw it, thought "Cool! a GUN! Let's play with it!" Said "guest" picked up the piece, drew back its slide and released it several times, couldn't understand why no cartridges flew out (no extractor, boys and girls!)The thing never worked right afterwards.
The offender was summarily ejected and told never, ever, to show his face in that place again, after which I pointed out to the friend that HE was a bozo to leave his weapon lying around where bozos could get at it. I also pointed out to him that it has always been considered extremely horribly rude, in all times and at all places, to pick up another man's weapon and play with it without his permission.
I believe I also said to him that the traditional punishment for such rudeness (well, anyway since the invention of the flint knife, or maybe even the sharp stick) has always been immediate, painful, violent death!
Are we so decadent that we don't know what our Stone Age ancestors knew?
Keep your hands off the other person's weapon, or else!
Edit: To distill it down to a blunt point (not to mention metaphor miscegenation), that guy is lucky to be alive! Had it been my dangerous short-tempered sweety there instead of your obviously cool-headed prudent spouse, there might have been a dead rude person lying there.
