Having read through the thick and think the 100 posts, and as a long married guy as well as a Christian, I understand the issue of marital disagreements.
I carry 23.5/7/365 and have for most of our 39.8 years of marriage. She knows that I would kill or be killed for her.
In the end, her objections are to be taken seriously, what aversion does she state? As you must know, marital discourse must be resolved by a mutually satisfying solution.
Show her your live and commitment by seeking out her issues and offering solutions.
Has she had bad experiences with violence? From a man who should’ve been a protector? Have you ever scared her past her limit?
Has she been the victim of violent crime?
Women are far too complex for a simple answer. Usually.
Do the foot work and find out her needs, ignore the ball busters, even though in a rough sense(and I happen to be rough man) they are right, but not correct.
Be the leader and not a tyrant. Pray for a solution.
It's actually the exact opposite. She's lived in the city her entire life and has always seen potential violence and removed herself from it. She has a lot of faith in that ability, and I've seen it at work on several occasions.
The main issue, I believe, is that she's not comfortable around weapons and generally sees the potential for mis-use, not that I've ever done anything along those lines.
FWIW- you didn't mention this, others did, but she has a profession where CCW would be absolutely impossible. I think her work friends factor into this aversion as well.
I appreciate your insightful input.
