Dunno why, but worrying about "proper nomenclature" seems to have become more prevalent in these last twenty years or so.
The clip vs. magazine thing stands out as a prime example. As a kid, hanging out in a gunstore and drooling over all those neat things that I couldn't afford, almost everybody used the word "clip" more often than "magazine". So, I grew up figuring they were interchangeable. So the years go by and I learn the difference between "arsenal", "armory" and "magazine". And I learned about stripper clips.
So the decades go by and I get into sometimes teaching somebody how to shoot a handgun. I drag out the old 1911. Only after basic "show-how" so that they get some familiarity and the beginnings of skill do I get into nomenclature. I quietly point out that some people get all exercised and upset if a 1911's magazine is called a clip. I did not, however, get into that subject with my grandfather, who'd been shooting .22 rifles and loading their "clips" since somewhere around 1895.
FWIW, "Native American" is another Johnny-come-lately thing. Me, having been born here, I figure I'm a native American. My forebears started showing up during Colonial times...
