I disagree, it has been explained away very well. To the point where it is only relevant today.
You need to compare the situation today with that in Europe. Federal guns laws bearely touch on the right. In Europe it is rare to find guns in the hands of private persons. Hunting in Germany, for instance, is much more tightly controlled than here in the states. If it much more difficult to hunt here than it used to be, it is because the scarcity of places to hunt has made it a sport for the well-to-do. Most restrictions are state imposed, and it is harder to argue that states have no right to regulate the use of guns.
