Are you willing to say every other gun owner has your training and does the same?
Nope, besides civilian training I also have more than 20 years military training. Every smart parent will teach their children firearms safety whether they have firearms in the home or not. That would include taking them to a range and letting them see the power and destructive capability first hand. It's not a one time thing, it has to be enforced over time. I honestly think it should be required in every school.
To give you an idea of how much the public mindset has changed just in my life time. Just before Christmas in 1962, I walked to our local Western Auto Store and bought my dads Christmas gift. I paid cash for a new 20ga shotgun and a box of shells and openly carried it back to our home, keeping the mussel pointed in a safe direction at all times of course and no one said a word. I was 11 years old at the time.
