Funny, the time I almost got stabbed was in a walmart parking lot, it's at least a little warzoney depending on locale. Glad you live in a nice neighborhood though!
(Before you don't look at unames I'm a different guy)
That's pretty standard in retail. Some get smoke breaks, some get stab breaks. Walmart just goes above and beyond and loves to help their customers even on their breaks!
To prepare for peace one must prepare for war. I have no delusions that I am some secret spec ops action hero, its more that me and other citizens be8ng armed changed the calculus for people that would want to oppress us.
This is a weird fantasy gun people like to imagine. There will never be a war like that, nor do they need to confiscate anything to control you. They already do through laws and your bank account. There's zero chances that gun nuts will suddenly rise up and start fighting the government.
It happened in the Ukrainian revolution, the police were sweeping the streets beating people with batons, some protesters we fighting back with rubble, but when they managed to get the guns the police were using on the crowd things changed dramatically.
In my personal experience whether not a place had armed citizens changed how cautious police were in that area, they may push and fuck with people they thought they could but were more likely to be trying negotiate with people on more equal footing as them.
No doubt there are other methods of oppression then men with guns and batons marching in the streets and fighting those require different tools and tactics.
