You should acquaint yourself with the definition of "weapons of mass destruction."  It doesn't refer to weapons that kill dozens, or even hundreds, but rather, weapons that kill tens- and hundreds of thousands, even millions, with a single use.  The term is usually limited to nuclear, chemical, radiological, or biological weapons.  Oh, BTW, "guns designed for war" generally can't be sold in the United States, at least not without a Class III permit, a tax stamp, a very stringent background investigation, and a whole lot of money. "Guns designed for war" all have one thing in common... select-fire capability. It's the key factor that makes a simple semi-automatic rifle into a real "assault rifle" (as opposed to the made-up political definition).

Your hyperbolic misuse of terms doesn't do much for your credibility, but then again, since your arguments are completely emotion-based, I don't suppose it makes much difference.
