The problem with "call them what you want" is that real statistics for "Assault rifles" are mixed in with "Assault Weapons" when cited by the dems - which is ironic to say the least since any actual machine guns used in crimes are post 1986 era guns (which are banned from civilians - so that sort of actually says the opposite of what Feinstein wants us to know), and already illegal (and most likely fast and furious guns).
My point is - terminology matters when the other side is using all of the spin and lies they can.
