Nope. Wrong. Willing to, yeah whatever, but it's not explicitly required. Kneecaps are non lethal.
I use to have the same "elitist" attitute being a trained 'professional' in a past life. Now I realize that if someone is willing enough to own and train with a gun , they implicitly are willing. So you just train them when and when not do, and what to aim for.
Because if it hits the fan, and I can't be there to draw quick to protect them, I am NOT going to be the one they blame for not being able to protect themselves.
Let It Fall, I have two sons , now 10 and 13. For the last few years I have encouraged them to open the cabinet and go through it. Take them shooting anytime they ask now, but made a point of going to the range as soon as they were old enough. I wanted them to lose their curiousity of firearms, and replace that with a repsect for, understanding of, and enjoyment from.
Oddly, the youngest one, who can handle an AR quite well, thank you, had no prior "gaming" experience when I first allowed him to shoot real firearms., unlike his older brother. Well, moms and dads, I'm here to tell you that gaming experience somehow makes for very sloppy gun handling habits in real life. I have to watch the older boy like a hawk, while the younger one always has the action open when done, safety on when loaded and the muzzle always pointed the right way. Go figure?
