To my knowledge no one. However, there are people on the political spectrum who would like to curtail or eliminate gun ownership. If you are a gun owner who believes that firearms offer a means of protecting yourself and the government wishes to take away the tool of that protection, I could understand why that may be concerning.
I'm not voicing an opinion on this one way or the other, I was mearly stating that I could understand the concern. Perhaps I misunderstood the GP's comment.
The idea that a free person has the right to self-defense is based in something you are. For some people, banning
the ownership of guns is an attack on who they are. This is true for some people who don't currently own guns as much as those who do.
