Full auto guns are protected by the 2nd Amendment..and have about a 100 year civilian production history in America - 1886-1986.
"Full auto guns are protected by the 2nd Amendment"
Congress says otherwise, and the Courts haven't struck down Congress, so no, full auto guns are not protected by the 2nd Amendment. Maybe you think they should be, but they aren't.
It's the wrong fight.
Focus on handguns and private carry rights. THAT'S where the protection of individuals is greatest, and it's a fight that can be won.
