I don't find it surprising at all, I think too many people try to pigeon hole others into a category, which isn't always so easy, "it's complicated" is a reasonable answer but not everybody knows how to deal with it.
As an engineer I see a gun as any other precision tool (no much more dangerous than a saw or hammer) which is why I consider this fascination with "carrying" open or otherwise to be strange. I like my miter saw but I don't need to have it on me at all times, the same goes for my ratchet set or Wera driver (though those would be handy to have all the time), but by the same token I always (save for airplanes) carry a full size Swiss army knife, which I mainly use to open boxes, beer, and sometimes electronics, though that is considered a weapon by some (I think of it as a tool, but hey). I guess it's just a question of degree, I feel unprepared without my multitool others can't live without their Glock. All I can add is just keep it away from the kids, to many bad things happen due to unsecured weapons.
