Guys....if there's anything to be learned from studying how legislation is crafted, it's that people don't pay attention to the specific grammatical interpretations of what they write. And if we're going to start getting into divining intent and looking at what words meant in 1776 versus now, you start to get into a whole new level of exegesis.
It comes down to the same sort of argument you see over the Bible: do you treat it as a literal, carved-in-stone legal document or as a guidebook whose intent should be followed? And not surprisingly, you see a remarkable amount of overlap between the two camps. Biblical fundamentalists tend to be strict Constitutional constructionists. Apparently there's a certain shared appeal in living according to laws that are never updated.
And this is why we need the right to own weapons. Some people will take it as holy and launch an invasion of your space due to it, and if you don't defend yourself your land gets sacked and looted.
On a more serious note, the constitution is open to interpretation, but it is generally interpreted based on the definitions of the words at the time.
For example, Militias from then are also called "Lynch Mobs" now (when they were commissioned by the local leaders). This is probably the source of the 'well regulated', to remove mobs that are acting outside the laws and with only the purpose of murder and mayhem. A posse is a "well-regulated militia" and it used to be an important tool of our law enforcement back in the days.
I do know that many of the states were afraid of tyranny, and only the threat of outside invasion caused them to join up with the majority of the group. As such, you can bet your butt that they did want to have the right to continue to fight against tyranny if it occurred again. Also, arms includes swords and crossbows, as well as nuclear weapons. If I built a nuclear bomb, I could probably argue, justly, that it is my right to have it. Of course I don't think the state would respect that and that my right to bear it would be infringed quite quickly.
How would that sit with everyone? Both sides. If the Supreme Court ruled that I could not keep a nuclear weapon I built from scratch, would you agree with their decision? That's a much better debate than a puny handgun
How about flashing THAT around a bar?
