Who is the more stupid?
The rifleman certainly is ignorant (lacks knowledge).
The pistoleer has knowledge, but passed up an opportunity to educate a fellow shooter.
Which is the more stupid act? The individual range may be safer, but the next range is not, nor the rest of the world and for an indeterminate length of time.
Maybe we do need a forum dedicated to the ridiculous, sublime and just plain crazy. It would serve as a repository for cautionary tales, education and occasionally, humor.
Good idea, wizrd. It would probably fill up fast.
