Yes, agreement to the various posts. Madison made it very clear, due to the actual conditions surrounding ratification of the Constitution, that a well regulated militia AND personal right to bear arms are necessary.
By focusing on the right of handgun/rifle ownership, we miss the larger intent of the amendment, which is to empower the states and give them opportunity to challenge the power of the federal government.
To incorporate the 2nd amendment under the 14th amendment would "federalize" the 2nd amendment so that this empowerment would havwe to be applied as an equal empowerment to the states. This will not be allowed by our Supreme Court. However, due to the nature of the 2nd amendment, it doesn't require the approval of the Supreme Court, since the very point was to allow equal empowerment between states and federal government. The amendment simply cannot be incorporated under the 14th amendment because of the problems it would cause to the feds.
States, therefore, are allowed regulation of firearms as rifles/handguns or "weapons of mass destruction" without recognizing the more important aspect for which the amendment was created in the first place: to empower the states equally with the federal government.
Today, the second amendment is being employed technologically by bypassing the strict interpretation of firearms. The internet is a far more equalizing power, and it is being used in the fashion that the 2nd amendment was originally intended, to empower individuals against the state and against the feds.
The "right to bear arms" is not precisely defined, but since "arms" were primarily rifles(which the literate Bostonians actually improved with a rifled barrel to outshoot the British Brown Bess), the implications historically would be that whatever arms are developed by the feds should be equally employed by the states.
Consequently, "a well regulated militia being necessary to a free state", would be translated into " a well developed communication system being necessary to inform a free people, the right to bear arms shall not be infringed".
