I believe A is legal in many states. Not sure about B, C, D - menacing behavior like that would be disturbing the peace or terrorism as you say.
What decent gun owner would walk around "waving his shotgun"? That sounds crazy, who would do that? Gun owners are people. Like, normal good people - neighbors I would probably trust. Does your view of gun owners differ?

There was no mention of the decency or otherwise of the hypothetical people, and it didn't read like they where intended as a moral illustration of gun owners in general. Sounds like you have a defensive agenda.

So we can observe that some of the hypothetical people, who may or may not be gun owners, who may just be gun borrowers, are probably not, in this case, decent and probably are intending to menace.
