Why do you assume they are absolutely fucking terrified vs thinking better safe than sorry?
I know the risk of a violent encounter is low, but I carry because it's the only reliable way to not be at a disadvantage in a fight.
Having a plan to avoid being assaulted isn't the same as living in terror.
Protip - if some group seems totally ridiculous, there's a good chance you don't understand something important.
Do you honestly think that panic attacks by gun carriers is the blocker to reasonable gun laws? The number of people that carry firearms regularly is not statistically significant, let alone those with panic attacks.
I carry a concealed firearm because I think it's important for at risk groups to be able to defend themselves. I don't panic when I don't carry, but I recognize that I'm less prepared to defend myself from assault.
It's important to understand those you disagree with.
