I think I see what they’re getting at here.
I talked to a family member not too long ago that bemoaned the availability of “semi-automatic rifles” -
it was clear when I challenged him to define the term that he thought it meant “select-fire”.
I’m betting these hoplophobic gun illiterates are making the same connection in their minds.
I think they know exactly what they are but they just want to ban everything they can get away with.
