I have too many personal experiences with people who have been terrified of guns - just the piece of metal and polymer scares the hell out of them. Then, as I expose them to more facts, point out more people who we both know who carry and/or own guns, people who they agree are "normal"; they see me carrying daily, and ultimately end up going to the range with me to shoot guns on their own...they start to realize "hey, this piece of metal and polymer isn't evil...it's just a hunk of material that I can control easily, and if I use caution, it won't hurt anyone at all".
THAT is the eye-opener for people.
I believe that the more good-guy-guns we have out in the open, the better off we will all be. If the ONLY experience people have with "guns in public" is criminals shooting at each other, or at the family as they carjack them, or at the cops as they try to arrest them...well DUH, they're going to have a fear of guns. We need "good guns" out in the open, so the fear gets put back where it belongs - fear of the CRIMINAL, not of the weapon. But first we need laws that support more open carry, in more places...and once we get those laws, we need to take advantage of them. Legally. Politely. Calmly. Much like was done in Richmond recently - be the better person, every step of the way. That way, when a scaredy-cat calls one of us in for open-carry, we will be prepared for a calm, polite, rational discussion with the officer that we are in fact legally carrying our firearm and have done nothing to make people nervous other than having it on our hip.
Is 11 pushing it? Meh...maybe. But, it's not like she picked it up on the way out the door as a prop, for the shock factor...she is literally a walking example of responsible usage.
