I disagree. I have been shooting from the time I was about 6. Moving from BB guns to 22 rifles to large bore rifles and handguns.
It was a fun, educational, and enjoyable experience and provided me a means to connect with my parents/grandparents and kept me outdoors and engaged.
Kids should be shooting, but in controlled and well supervised environments. I was taught to respect firearms and to understand their danger and their utility. That is what should be done.
However, I do agree that parents who do not secure their firearms or let kids play with them like toys should be charged. I didn't have access to my guns as a kid unless my father got them out and I would have lost my privileges if I ever did anything more than pick it up, point it down range, fire, then put it back on the designated area.
