It's taken far too literally by too many gun enthusiasts. Rather than a caution against brandishing and threatening when unwarranted, and a caution against hesitating at the wrong moment, it's seen as a hard and fast rule. We have an excellent example of how guns used as a threat, rather than being pulled only to shoot, is a great thing that saves a lot of lives. For prideful reasons related to GADS, or Gun As Dick Syndrome, people think that pulling a gun in self-defense without firing it is some holy action that only a certified, trained, and knighted officer of the lawrr is qualified to comprehend.
Dead Men is not a cynical response, it's a nearly universal admonition by GADS sufferers to empty the clip into any person you decide to shoot.
