You “Dodged” The issue(no pun intended.) Why did the folks of those days, in the towns mentioned, pass the laws restricting, in their town, the carrying of a gun at will? Not one open carry fanatic(a dangerous being), will ever answer the question. Tell us why the very people who once lived under unrestricted carry rules passed laws restricting carrying? Answer the question if you can.
Once again there is NO unrestricted Constitutional RIGHT. Open carry will prove to be a disaster and a repeat of Dodge City 1876.
So, you're resorting to slander (actually, libel, here), in calling all of us who choose to open-carry a "dangerous being". Thugs are dangerous beings. They tend to not open-carry.
To answer your question on why they banned guns in many "old-west" towns? They were like you. They thought everyone with a gun was a dangerous being out looking to kill someone, and they wanted total control over their citizens. Facts be damned. Criminals and governments are the only ones who benefit from gun bans.
