Sorry but history proves you wrong; most often when a law is passed allowing folks to open carry the majority don't carry properly; young students like to show off their toys and when they start drinking it doesn't get better it gets worse; plenty of students have been killed on open carry campuses so your theory really doesn't hold water.  If you feel you need your gun everywhere keep it in your car.  Some of us are better equipped in hand to hand combat and in close quarters a gun is less effective; how do you disarm a shooter with your own gun with a mass of bodies running around? More likely you're apt to shoot a bystander and end up in jail for being a sloppy shot.  

Being equipped and ready isn't just packing a gun with you everywhere.  Some of us can be just as deadly without a weapon than you are with one
