This is such a weird take, but I hear it a lot. Many of the people I work with carry and very few of them are like that.
I think there are cultural differences, though. City people are more likely to be that way, but for the more rural or country guys it’s the same as me carrying a knife all the time. It’s just something that’s done.
Not so weird… A Knife I can understand. There are a number of uses for a knife beyond being an offensive or defensive weapon. I’m not a knife person, personally, but even I have a few to cut food, or open sealed boxes. I’ve seen knives used to cut bindings and they can even be used to craft art (whittling being an art form where the knife is the primary tool of choice)!
A gun? Outside of a legit, active warzone? A gun either says you’re hunting, or your scared. That’s it! I have all the respect for a hunter going into the forests to hunt game animals. I do love myself a burger and a steak… but in a public setting? What’re you hunting? What utility is a gun in a public Walmart?
