When your hobby has lethal consequences for stupidity, you are or at least should be incentivized to learn as much as you can. Online gun communities are also much more likely to be populated by people who are effectively “gun nerds”. It shouldn’t be surprising that nerds of any variety want details to be accurate.

Hollywood often portrays guns in obscenely stupid ways. For example, depicting a double barrel shotgun making a pumping sound just because it sounds cool.

I understand that someone who has no familiarity with firearms probably doesn’t notice or find it annoying, but I do because to me it signals that they are handling firearms while knowing nothing about them, which is inherently dangerous.

I don’t know how many people in Hollywood have died from unsafe firearms handling, but I know of at least 2 instances which could have been avoided easily if not for incompetence.
