No, it's about the almighty dollar and the gun manufacturers making money off of a model that they initially couldn't sell very well to the military. It's about feeding off the paranoia of the average citizen. When you talk about "parity" you should remember that the NRA propaganda just 20 years ago was swearing that ANY gun control was a slippery slope to total gun confiscation and ban to the civilian population. By that take, you state that weapons of ANY caliber are a threat of resistance to the potential totalitarian/fascist/communist state. Any soldier worth his weight will tell you that they would rather NOT face a population armed with hunting rifles, rifles, handguns and shotguns of various caliber.
The militia is the "parity"....and that today is the National Guard and various state recognized & sanctioned militia. Other than that, the average citizen does have a right to a weapon....not a military grade one.
Well we know that the NRA blather NEVER had a chance of happening and was NEVER part of any proposal. The AWB of 1994 was an attempt to keep para-military weapons out of the general population and thus subsequently off the black market and out of the hands of potential nut jobs and terrorists.
