It was a joke, darling. You worded it funny.
There's a difference between "sheltering", and exposure to appropriate materials at appropriate times. "They're gonna see it anyways " is lazy, piss poor parenting. If you want what's best for your kid, you don't just accept whatever bullshit and not try to do anything about it.
Control the things you can. Throwing up your hands and saying "fuck it" is not how to raise a kid.
And lol at "unarmed combat being a way of life" Since when? For whom? Even centuries ago, it wasn't like everyone was a fucking warrior.
Centuries ago you married your cousin when you were 12 and died at around 40....ah....the good ole days.
