let rephrase : for me a kid should be kept as innocent (or candid) as possible you cannot let a kid play with a gun without learning him the purpose of a gun <period> and doing so you trash his innocence.
If you don't learn him you're about to make a kind of child soldier and so are a criminal to me.
You don't buy I'm a former shooter ... as you like.
May I remember you service was mandatory in France in the 1990 when I was 20 ?
And it's the part I had to do, not the one I was doing on my spare time with my uncle and others 
<edit> my kids ( 6 and 8 ) are not doing any pixel shooting on and off line,they're not ready to do so.
LOL.. same 'ol Straffo. Swingin' fer the fences and still striking out.
Point: Women & Kids should be competent with Firearms. How else will they be able to deal rationally when threatened with one? My kid can tell make; prime features and fire condition... at a glance. Makes her safer.. and a lot harder to abuse or kill. And should she get control of the weapon that's being used to 'control' her, she'll be able to use it.
It's unfortunate that criminals can obtain weapons easier than lawful citizens... and as long as that condition prevails, turning over security of the family's personal safety in an environment where roving gangs of thugs and street critters walk about looking for victims for fun and status and the 'police' are constrained by competence, credibility and corruption...
The right to keep and bear should not be an 'age' issue.
