>Common in rural US. I was taught at about 4 or 5 the basics and gun safety.
Ofcourse it´s common, there´s nothing else but cute about it. He´s loving it, it´s a cute trick for him, that he´s proud of showing off that his dad or someone taught him. These fucking lunatics like that twitter guy freaking out over a kid knowing gun safety. Let´s just go through the mind of the insane american ´liberal progressive´ when he sees this.
>omg the 4 year old kid knows how to reload a gun. 
>he´s going to grow up and kill everybody when he grows up because he knows how a gun works. OMG literally shaking right now. We´re in hell this is a nightmare wake me up inside. 
These fucking mental patients. They are so unused to being in reality that they don´t understand well, reality. They don´t get it. I don´t know what kind of a bubble reality they live in, i guess it´s one of those that live in some kind of extremely hipster area in a big city and never goes outside of it. Completely useless unless someone else creates their little urban bubble reality for them.
I can´t for the life of me understand why ANY american is afraid of guns. I CAN´T UNDERSTAND IT. I laugh about it when i see it EVERY SINGLE TIME i see one of these fucking retards on social media scared of guns HAHAHA. It´s a tool, might aswell be scared of a kitchen knife, or a screwdriver. Almost anything can be used to kill someone, even mundane things if you tear them apart a little bit. But people don´t do that. Unless they are crazy.
