It is trivially easy to think of an example where the intent is the fundamental point of dispute: the ACLU vs. the NRA's interpretation of the second amendment.
So let's talk about that in terms of original intent then, it's a good example of how this works... Looking at original intent, what DOES the 2nd amendment say? What did the founders intend when they wrote that? What right where they trying to protect?
The text of it says: "A well regulated Militia, being necessary to the security of a free State, the right of the people to keep and bear Arms, shall not be infringed."
During the 2nd world war, it was said by military leaders in Japan that they NEVER wanted to invade the USA because "there was a gun behind each front door". I think this was the intent of the framers, to provide an intrinsic armed populace that could muster a defense of the country. That's how the revolutionary war was initially waged, private arms owned by private citizens, fighting for their independence.
So what's the left's out from the "the right of the people to keep and bare Arms, shall not be infringed?" I don't know, but it seems to me that it is a whole lot more strained interpretation that says something like "What's a well regulated Militia?" and how is that related?
So, at risk of misstating your side on this debate, what IS the original intent argument here that supports this "Ban Guns" mantra of the ACLU? I'll let you respond.
