A set of excellent counterpoints. I’d also point out that “gun nut” is quite different than “2nd Amendment nutter”. You’re into guns. Maybe the mechanics, maybe the design aspect, maybe you enjoy shooting as a hobby, maybe all of the above and more. That’s fine, if you’re also a responsible gun owner who secures their weapon, does not leave it loaded when off your person, does not point it at something they don’t intend to destroy, and so on and so forth.
A “2nd Amendment nutter” thinks the 2nd Amendment absolves them of responsibility.
