Below is a surprisingly good resource on understanding the controversy over the right to bear arms and what does that exactly mean.
I believe everyone has the right to own a gun if they wish. Having the right does not translate into everyone wanting to own a gun (for example, my mother doesn't want one in her house and she grew up in a household where having multiple guns was the norm) or suddenly our nation becomes the wild, wild west (anymore than it is right now).
My grandfather Walls loved guns. He could not afford the higher quality guns but he loved what he had and enjoyed target shooting and hunting. He taught his children how to use a gun. His wife, Margaret, was a champion sharpshooter as a young woman. To Grandpop, the weapon was nothing more than a resource to use to put food on the table and defend the family if necessary. The denial of his right to have a gun would have made things difficult for his family.
