Sorry, the wording of the Second Amendment does not have to explain the right. It says what it says. I will continue to have a “knee jerk” attitude toward denial of that, regardless of whatever reductio ad absurdum arguments may be presented in opposition.
So you agree the Second Amendment protects the right of five-year olds to publicly carry NAA revolvers, fully loaded, cocked , with their fingers on the trigger and the right of someone to publicly wear a suicide vest with a dead mans switch in their hand.
