Shouldn't all states be open carry since we have the right to bear arms?

Shouldn’t all states be open carry states? As much as popular pundits would have believed back in the days of the early West when nearly everyone, men and women, carried their six shooters on their hip it was not a wild lawless place. People carried firearms and knew how to use them, and had little hesitation to use deadly force to protect their life stock, property and family. Incidence of robbery and such was not as much in comparison to today because any would be thug knew the owner of the home would be armed and likely to fight back. If open carry was the norm today these home invasion robberies and carjackings would be very rare. Don’t you feel that all the fear of open carry laws are political hype? Why do we have the right to bear arms if you can’t really bear arms?
