I understand the exact point you're trying to make, but some people act like they have seperation anxiety from a gun, if it isn't on their hip.
Man the fuck up, you'll be okay with it left in the car.
Let's be honest, in a situation where someone might pull a gun and shoot someone in a bar or parking lot, I bet 80% of you would climb under a table and suck your thumb out of instinct. Everyone thinks carrying a gun will also make them a hero, and it's just a delusion of grandeur, and in my opinion, a false sense of security. If someone wants to shoot you, they're going to do it before you can react.
I think a weapon at home to protect your property is fitting, but carrying in every single establishment is a little much, IMO.
