First off, nobody is arguing FOR automatic weapons, nice straw-man. But let's imagine what the founders intended.

I own a musket for home defense, since that's what the founders intended. Four ruffians break into my house. "What the Gov'ner?" 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, but it misses entirely due to smooth bore and it hits my neighbors dog. I run to the top of the stairs to my black powder cannon loaded with grapeshot. "Tally ho lads!" I cry out as the grape shot shreds two men to pieces. The sound and extra shrapnel set of car alarms all over the neighborhood. Fix bayonet to musket and charge last terrified rapscallion while shouting "Take this scallywag!" He bleeds out waiting for the police to arrive since triangular bayonet wounds are impossible to stitch up. I look up at the American Flag waving from my flagpole and a tear comes to my eye. All just like the founders intended.

Then again, freedom of the press only applies to printing presses that were available to the founding fathers. You can't have these high capacity semi-automatic printing presses just printing out entire books at the push of a button. Also, you can't just have a guy type something out and send it around the world on the internet, he should have to stamp it out page by page on an old school printing press and hand out flyers on the street corner like Thomas Paine. Just like the founders intended. People shouldn't be allowed to advocate 2nd Amendment restrictions online, only if they are using a 1700's printing press, otherwise freedom of the press doesn't apply right? The founders never would have imagined the internet to let dumbfvcks like you annoy people online would they?
