The fact of the matter is, everyone has a personal meaning they ascribe to the Second Amendment. However, this has little bearing on how gun control and gun rights are legislated and adjudicated by the states and federal government.
The idea of the Second Amendment providing a right for personal gun ownership is only a very recent development in our constitutional jurisprudence. In DC v. Heller, SCOTUS decided 5-4 that there is a qualified right to personal gun ownership for the purposes of self defense. The relevant language, written by Scalia himself:
“Nothing in our opinion should be taken to cast doubt on longstanding prohibitions on the possession of firearms by felons and the mentally ill, or laws forbidding the carrying of firearms in sensitive places such as schools and government buildings, or laws imposing conditions and qualifications on the commercial sale of arms.”
“We also recognize another important limitation on the right to keep and carry arms. Miller (an earlier case) said, as we have explained, that the sorts of weapons protected were those “in common use at the time”. We think that limitation is fairly supported by the historical tradition of prohibiting the carrying of ‘dangerous and unusual weapons.’ ”
Therefore, SCOTUS did not grant an absolute right to own firearms. They purposefully left the door open for states to regulate the commercial sale of firearms. Everyone here can shout to the moon one way or the other, but it does not change the doctrine. As long as your home state has a majority of legislators that see the 2nd Amendment as an expansive right, you will not get the gun control you seek. As long as your home state has legislators that seek to introduce reasonable gun sale policies, you will get the gun control you seek. There is no absolute right to own a firearm, despite what you may think Heller stood for. So, if this is a tremendously important issue for you, vote for the single issue. The important thing that is getting lost is that a lot of people died today. Grief and sympathy.
