Are gun range parties, reckless, or a fun way to start a healthy weapon respect early?

Now I know there will be too opposing forces because of the “ick factor” many have against weapons themselves, much less in the hands of perceived babes. What would be so wrong with gun range or target shooting parties slanted more towards children and young teen adults? If they are tightly supervised (which I believe they will be), the up side is they have a healthy respect for weapons, and receive proper training on how to use a weapon, and to keep it safe with proper cleaning and safe securing (tipping my hand on what I feel of it). I can’t see how any of those youngsters will be able to go amuck and shoot up the place.
