It was not the NRA that pushed for this interpretation. If you are interested in the Second Amendment, I recommend reading this US Supreme Court Case opinion in full: https://www.law.cornell.edu/supct/html/07-290.ZO.html https://www.law.cornell.edu/supct/html/07-290.ZO.html It explains the meaning of the words and phrases, and their intention, and provides ample justification in the way of founding-era sources. > There are many reasons why the militia was thought to be “necessary to the security of a free state.” [...] When the able-bodied men of a nation are trained in arms and organized, they are better able to resist tyranny.
