There are a large number of people in the United States with permits to concealed-carry firearms.
I carry my gun with me 97% of the time. I work at a screenprinting shop and the owner doesn't mind, and most places that I hang out, it's permitted at well. I can't take it in the post office, schools and colleges, bars, casinos, etc, but aside from class and the post office, I have it in my pocket almost all the time.
It's just like carrying a knife or a cell phone, it's part of what I put in the pockets when I get dressed. It's just a tool that I carry with me daily. It's relatively unobtrusive, and I pray that I don't need it, but if I do, at least I know I have the ability to defend myself and my loved ones.
It's really not a fear thing, there are [rare] days where I leave it at home, and I mostly feel fine, but at least my having ensures that I'm prepared and can pose an equal threat to anyone who may threaten me, that's all.
What he said and it was very well said.
When I don't carry a firearm, I carry a knife.
