If I was the only one who felt that way sure, but I'm not. Most non gun owners are scared of guns in my experience. Open carry is frankly extremely disrespectful. I don't know what you're going to do with that gun, and I think it's a mistake to think of it as anything other than a threat. And threatening literally everyone you see is a dickhead move. Not really sure how you could see flashing your gun at every random person as not a dick move, the only reason to do it is to scare people.
It absolutely is a threat. "Good guy with a gun" incidents are so much rarer than "bad guy with a gun" incidents that it would be insane to see it otherwise. Nobody knows you're not the next Kyle Rittenhouse who, in the absolutely most charitable interpretation I can think of, might not have meant to kill anyone but ended up with a body count anyway. Or the next mass murderer, whose names I will not repeat. If I walked around with an unsheathed six-inch knife I'm pretty sure people would quite rightly feel threatened, and literally any gun is more dangerous than that. So yes, "dickheads" does apply.
