Heh so are tanks and machine guns- he probably thinks those are perfectly harmless too.
Good news! Barbed wire no longer punctures skin.
No, I don't think tanks and machine guns are weapons mass destructions, indeed I think people should be allowed to own whatever the standing army owns.
That said, I bet the ATF would love to classify all guns as WMDs...and I bet you could be duped into supporting that notion, Leftie.
