You can always just give the muggers everything, including your gun.
You can't barter back your (or your family's) life, and putting the massive asymmetry in the benefit of the doubt of a known assailant is maddeningly naive to a point of near literal cuckoldry.

Don't try to impress people with words, impress with ideas.
That's just your perspective and talking point. Parent was clearly trying to say that there may be a situation where you DO need it to protect yourself or family from being killed/raped/etc.
Having a weapon on yourself in preparing for the worst case scenario. "Hope for the best and plan for the worst", you know.
Of course given that muggers expect you might be armed, you might as well be. But I'm still not convinced they actually make you safer; lots of Americans get killed by their own gun.
