A lot of witty answers here.
I agree with the sentiment that its best not to be a "smart-@ss" or aggressive with answers.
Let's face it guys.
There are two VERY significant realities in our world:
1. EVERYONE in our society seems just itching to pop off at the mouth to someone else. I don't know if it has always been this way, but it seems that our society has gotten much more confrontational in the last decade.
2. Non-gun persons often have a underlying "belief" that anyone that carries a gun is just HOPING to shoot someone. They are fed the media image of a gun-owner and they have shallowed it hook, line, and sinker.
Now, operating from the above two "premises:"
Calmly state that criminal activity is a daily occurence and much of that activity occurs in parking lots, side-streets, parking garages, etc. Calmly state further that your life and the lives of your loved ones are worth more than hoping bad things don't happen to good people.
End that with "have a nice night," or "I hope you enjoy your movie."
You will have FAR more of an impact on such a person by NOT being the stereotype that she is carrying around in her subconscious. You will likely knock her off balance. And what you WILL do is show that you are a respectable, and just as important- respectful person. This is nothing like she NEEDS you to be in order to reinforce her anti-gun (probably) beliefs.
Who knows. Once a person is presented with an uncomfortable reality such as how dangerous a parking garage or lot can be, it isn't much of a mental leap to her internalizing it and considering the possiblity that she could be robbed, killed, or raped on the way from the theater to her car. That seed could grow to make a pro-gun person out of her-- and maybe save her life.
Yes, I know that is unlikely.
What I DO know it will do is help the image of gun owners by showing one more person that we aren't what they WANT us to be in order to define us, characterize us, stereotype us, and then destroy us.
And you will have shown everyone listening to that conversation as well.
And yes... on the spot, I may well have done much different than I outlined above. However, I've learned from my wife that sometimes not being as "assertive" as I tend to be and being more accomidating can often win battles that I didn't even know I was fighting.
Thanks for bringing up this event. It's a good idea for us all to consider how we address those we must consider as our advesaries and how NOT to play into their hands.
