I would talk about it. More loudly and angrily than I would talk about a lefty, in fact. There are lots of conservatives that don't own guns, and may not even like to shoot, but they support the 2nd amendment. I hold them to a higher standard. If you're a conservative ACTOR that doesn't own guns, and you're in a role that requires you to handle them, and you consent to that, you still need to be versed in gun safety, the anatomy of a gun, and gun safety(yes that 2nd "gun safety" was intentional).
In the military, before you can be authorized to carry a firearm you have to complete a qualification process that starts with something called "PQS"(personal qualification standard) for the weapon you are going to carry. It starts with reading the manual, then you field strip the thing, identify the parts, correctly reassemble it, functionally check it, explain the procedures for correcting any malfunction, and the procedures for clearing the weapon and cleaning it. I've seen 18 year old's do it in less than 10 minutes(excluding reading the manual). And STILL incidents occur(I call stuff like that incidents, because almost everything we call an accident is actually preventable). This particular clusterfuck could have been avoided by having an NRA certified instructor on that set, and they probably could have gotten one for free.
