Own a musket for home defense, since that's what the founding fathers intended. Four ruffians break into my house. "What the devil?" As I grab my powdered wig and Kentucky rifle. Blow a golf ball-sized hole through the first man, he's dead on the spot. Draw my pistol on the second man, miss him entirely because it's smoothbore and nails the neighbor's dog. I have to resort to the cannon mounted at the top of the stairs loaded with grapeshot, "Tally ho lads" the grapeshot shreds two men in the blast, the sound and extra shrapnel set off car alarms. Fix bayonet and charge the last terrified rapscallion. He Bleeds out waiting on the police to arrive since triangular bayonet wounds are impossible to stitch up. Just as the founding fathers intended.

Exactly, bullets weren't even invented yet when they wrote the Constitution, but "conservatives" believe all these modern weapons are exactly what the founding fathers wanted to protect.

A feddit.uk account winging about Americans having too many guns? You planning something lobsterback? (This is a joke btw)

That law was added when guns were so imprecise it was difficult to hit the broadside of a barn from inside the barn.

That's blatantly false. Timothy Murphy killed a British officer during the Revolutionary War at a distance of 300-400 yards. They absolutely had the capability of precise marksmanship at the time the constitution was written. Repeating rifles were not a foreign concept either. They weren't common yet, but there was no reason for them to believe the technology wouldn't be improved.
