Anyone who doesn't believe in negative energy just needs to spend the afternoon reading USACarry forum posts (rimshot).
And, if you're going to support the right to keep and bear arms, you need to support the right for other folks not to. It's their choice, not yours.
That being said, I never felt strongly about carrying one way or another.
My husband wanted his CC permit, and offered to pay my fee for the class. I said why the heck not? It doesn't mean I have to carry. It just gives me one more permit.
I took the class and came out with a new appreciation for CC and OC. At first I didn't carry, and I would tease my husband every time he holstered up. "You expecting a gunfight at the WalMart corral, Hon?"
He would just smile and say something like "You never know" or "I'd rather have it and not need need it..."
After a little while, I thought, I have a permit, why not carry? Plus, I'm a little bit of a control freak, and as much as I trust Hubby with my life, I'd like to have a fighting chance, too, thank you very much.
At first I didn't carry every day, because I didn't want to have to think about it that often. Then I just decided to get a very small, carry-friendly bag. It doesn't mess with my style and I don't have to think about it. I could just grab it on my way out the door every day. I'm now at the stage where I'm considering on-body carry.
The more I researched and read, the more I liked the idea of carry. The more I carried, the more I researched.
I understand your wife's sentiments. I do believe in negative energy, and I believe that if you are looking for trouble, trouble will find you. However, for myself, I found that once I started carrying, I felt much more confident and projected a much more positive energy, as I no longer felt like any given situation could disintegrate into violence against my person.
I think the world would be a beautiful place if we didn't have guns. Honestly. Sunshine and rainbows and all of that. Much positive energy. But until that day happens, it's just common sense that I protect my little spot of sunshine.
