From Google:
"What is a straw man argument?
This occurs when, in attempting to refute another person's argument, you address only a distorted version of it."
Proponents of gun control have never, ever said that guns killed people all by themselves. This cartoon version exists only in your head and has no bearing on the real issue. It is a distorted view of the argument, invented by the advertising wing of the NRA and embraced by you.
Instead we believe that guns are used by people to kill other people.
We believe that if there weren't quite so many guns around fewer people would die from being shot by them.
We believe that if semi-automatic rifles were banned, people intent on mass shootings would have a harder time doing it before the cops arrived.
