This. I have always seen basic small arms as a fundamental military skill, just like learning how to march in formation and properly wearing a uniform. Even if you don’t know how to properly set up the optic, it should be obvious something (several things, in fact) is/are seriously wrong with that rifle, and you should hand it back to the armorer, not yet away like a hillbilly (who would likely know better, and suggest a fix.)
This one really speaks to our studied ignorance on firearms in general, which is a larger cultural issue. I’m teaching my kids basic firearm safety and marksmanship not because I expect them to like firearms, but because- in part- it’s a fundamental life skill that might help them recognize ignorance like this.
Ok, I’m really done now. Sorry, this one just grinds my “old man yells at cloud” gears.
