Fundamental, to me, means vital to existence, like air, food and water!
Very true...But the Second Amendment being “vital” to you, it is not to others, that (they) obviously do not believe you and I should be afforded this right...
So you and I, and many others who understand the issue, it is also bolstered (supported) by the moral and inheirancy of the authority that was recognized by a virtuous group of men who penned it...
Look at it this way, it is an issue that needs to be understood (or not), but regardless, it is one that needs to be left alone for free men and women to exercise at their discretion...
