If you don't get it your position is already clear. No one is going to change your mind.
You'd be surprised...I'm a sucker for logical arguments.
Maybe five years ago or so I was in a shopping mall somewhere in Kentucky, and I see this still wet behind the ears kid with a nickel plated Jennings 9mm hanging from his belt...and I can tell you from first hand experience that it made me nervous.
And I'm a gun guy...so I can imagine how much worse an experience it would be for someone who isn't comfortable with firearms in the first place.
