I started teaching my kids at age 7. The first thing I taught them was how to safely clear the weapon and how to clean it. I also stress respecting the weapon, I constantly remind them that a gun is a dangerous tool and can hurt and kill when it isn't handled properly. Then I stress how to properly aim and shoot. My daughter is 10 and can take a little .22 and just about shoot the wings off a mosquito.
Of course, she doesn't understand the marxist dialectic like a liberal kid, but she's aware of it. When I told her about it she said, "That's silly."
