To which I say, "Bring it!"
You're knee-jerking this, Bob, and I doubt you're going to find many on this forum who are sympathetic to your beliefs.
Millions of men in American history openly-carried their rifles, shotguns, and pistols, and I bet you couldn't muster more than 100 incidents CAUSED by those carriers.
Carrying a rifle in a mall is a deterrent, IMO. No punk kid, no emo or goth kid, no ghetto fabulous thug is going to approach that man and attempt to take that rifle or even JOKINGLY come up behind him for any reason. It's that sort of normalization that I'm talking about.
Inner city kids and thugs go up to innocent, peaceful Americans in almost daily-documented cases "playing" the "knockout game" or otherwise accosting them. Do you HONESTLY think that they'd even contemplate something like that against a man openly-carrying a rifle and a pistol?
If you want to be limp-wristed in the exercise of your rights, go for it. Personally, I will proudly walk the mall, the grocery store, and through any establishment that allows me to carry my weapon. If they have signs posted stating that they're a gun-free establishment, I shop elsewhere. It's that easy.
