I can’t promise this will satisfy you (you well know my intellectual limitations), but I promised you an answer, so here goes.
Essentially, you’re positing that the banning of certain kinds of guns is akin to the banning of certain kinds of speech, and suggesting that it’s hypocritical and self-defeating for me to fight against one less strenuously than the other. Is this a fair restatement of your argument? If so, let’s go on.
I) The Easy Answer. Ready? Here it goes: Sure. For the sedition exception to the First Amendment I’ll take a comprehensive automatic weapons ban, for fighting words I’ll take .45 caliber and over, for Incitement to Crime I’ll eliminate private sales and concealed weapons (and this is a gosh-darn gift, mind you- Second Amendment says nothing about selling or hiding the things), for Causing Panic I’ll take mandatory comprehensive background checks that can take a couple of months if necessary, for defamation – ooh, that’s a big one. How 'bout, for defamation I get a maximum throw weight, defined as projectile size times velocity. Oh, and for those damned unconstitutional “free speech zones” I get another restriction to be named later. Okay, now we’re even.
II) The Disclaimer. That answer doesn’t really satisfy me, either. For one thing, there is no real-world trade-off between the First and Second Amendments. As I’ve mentioned, my love for the First is the basis for my willingness to defend the Second. For another, there is no equivalency chart for encroachments on freedom of speech vs. abridgments of the right to keep and bear arms. But these faults, I think, originate in the original question, as I hope the following will explain.
III) A mush-mouthed and clumsy attempt to explain. I don’t accept the analogy that one gun, or type of gun, equals one speech or type of speech. There’s certainly nothing intuitive or analytical about it. The ability to say one thousand different things is inherent in the First Amendment in a way that owning one’s own armory is not implied by the Second. The right to bear arms is achieved a “fur piece” short of possession of every killing machine yet invented, but freedom of speech isn’t a reality as long as anyone is silenced. You may as well say that the First Amendment doesn’t allow you to talk directly to other people if the Second doesn’t allow you to shoot at them.
IV) A Gift for Those Who Disagree. I don’t know quite what to do about the argument that, just as the rest of the Bill of Rights was designed to give citizens both offensive and defensive weapons against oppressive authority, the Second Amendment, with its gift of armament, must have been designed for the same purpose, and should protect a balance of power between the citizenry and the government. I don’t know what to do, that is, except say Come on, guys! Where are you gonna keep your nukes and nerve gas?
