And you want proof that it doesn't....California.
That's just it: It was not routinely done in California. Then one day the Black Panthers took up arms.
Open Carry of loaded guns was banned ...... and who is gonna openly carry an empty gun? So nobody did. It was not viewed as normal, thus marginalizing the activists who insisted on trying to excercise their 2A rights. Once again, OhNOES! Scary people who are different from me got GUNZ! and all Open Carry was banned. Pay no attention to that incline, or the grease on your feet there, Californians........
