I don't feel like multi-quoting all the relevant passages but that instructor that gave an Uzi to a nine year old girl at a shooting range is a fucking retard. The kick from an Uzi is so powerful that you could point it at the ground and you pull the trigger and that bitch will buck up like a wild fucking horse. With an AR at least it is a rifle so you could teach a nine year old girl to shoot on that and it would be much safer because you could make sure they have proper cheek weld and that they seat the rifle butt in their shoulder. You could teach them prone and sitting shooting positions pretty safely. Even if you taught this theoretical nine year old how to shoot standing up there would be much much much less risk than handing them a fucking Uzi. The rifle itself is much easier to handle and control.

It's like I don't want to say I called it but if you would have told me that someone was teaching a nine year old to shoot with an Uzi I would have immediately said that guy is going to get shot. I'm a grown ass man and when I shot off an Uzi it took every ounce of concentration and a bit of strength to control it.
