I also go by the view that absolutely every gun is loaded. My sole exception is when I am working on a gun is that I will have my finger in the action and even then I do not just wave it about but I will look into the muzzle of a firearm when I have a bore inspection light in it. I was also taught that pointing an unloaded gun at another human being can get one shot quite dead as they have no way of knowing that it is unloaded.

Proper handling of firearms is a valid indicator of ones "ability" IMHO. As you stated if one sweeps himself or others , tell em in a loud and impolite manner for all to hear that such is just not tolerated.
Our local range has a disclaimer that states if an unsafe act is observed or reported your day at the range is at it's end. If you repeat an unsafe act then your gone for good.......hopefully only from the range :o)
Stay Safe !
