Apparently, the Left's New Claim is That the NRA Created the Indiviodual Rights Claim About the Second Amendment in the 1960s

 From Sen. Howard's speech explaining the 14th Amendment:

Such is the character of the privileges and immunities spoken of in the section of the fourth article of the Constitution. To these privileges and immunities, whatever they may be—for they are not and cannot be fully defined in their entire extent and precise nature—to these should be added the personal rights guaranteed and secured by the first eight amendments of the Constitution; such as the freedom of speech and of the press; the right of the people peaceably to assemble and petition the Government for a redress of grievances; a right appertaining to each and all of the people; the right to keep and to bear arms; the right to be exempted from the quartering of soldiers in a house without consent of the owner; the right to be exempt from unreasonable searches and seizures, and from any search or seizure except by virtue of a warrant issued upon a formal oath or affidavit; the right of an accused person to be informed of the nature of the accusation against him, and his right to be tried by an impartial jury of the vicinage; and also the right to be secure against excessive bail and against cruel and unusual punishments. . . .
