Totally agree.
This video shows a fully grown woman firing an Uzi which has a stock & pistol fore grip:
Any child would struggle with safely handling that.
Personally I've shot many guns over the years, not just airguns but also firearms ranging from muzzle loading 12 bore shotguns, rifles & various calibre revolvers/handguns. I obtained a certificate of marksmanship when I was just 14/15 years old from a firearms instructor in America which the training also covered firearms safe handling & use.
So obviously I'm not against guns but I would definitely not be putting a firearm into the hands of any children I may have.
