Yes, you're right about it being the people. That's a more nuanced approach to the problem. And so it's the guns in the hands of the people with a mindset of violence.
You shouldn't have to give up your guns.
And of course it will never be 'most' who shoot other people.
If say a hundred gun owners were lined up holding their guns, I would suggest that the one or two who will be involved in trouble of some sort with their guns, could be identified by their personal appearance and by the guns they choose to own.
Trouble as in everything to accidental shootings, vandalism with a gun, or crimes up to and including murder. Their mindset of violence could be measured somewhat by their choice of weapon and their personal appearance.
It's always worth broadening the conversation, if only to poke the extremists with a stick.
But much more is possible!
