One of the things I liked about the Rifleman was how they handled the aspect of the 'gun'.
I can think of two shows that ponted out the way WE (2A supporters) look at guns.
One was where a prissy male teacher got his panties in a wad when Lucas dropped Mark off at scholl with the gun in the wagon. Teacher said "Don't bring that killing machine near school'. Of course it ended where Lucas saved his sorry a$$ with that killing machine.
Another was when Mark got afraid of the rifle (can't remember why) but had to overcome his fear of it to toss it to his Dad.
Good lessons on mind set and reality.
