The next victim-disarming idiot who uses a smart phone connected to a computer network operating over fiber optic lines to tell me the framers of the Constitution and the Second Amendment never envisioned modern firearms, and that the Second Amendment only protects muskets is getting bitch-slapped.
James Madison, known for his role in drafting the Bill of Rights (including that pesky 2A) lived through the rise of repeating firearms, breechloaders, paper cartridges, percussion caps, metallic cartridges, pinfire cartridges, centerfire cartridges, revolvers, and mass production of firearms.
Heck, an early machinegun was pitched to the US War Office in 1812, and patented in 1813 — during Madison’s presidency (and was a refinement of a 16th century machinegun).
Yet never once did Madison stop and say, “Whoa, guys! We didn’t have any of this new shit in mind. the Second Amendment is just for muskets.”
