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.
