I Won't Let My Kid Do ...
You've got an idea about what it means to be a functioning human being, and the kind of behaviors that are acceptable or not for your kid to display. You might be wrong, but that's beside the point; your kid sure won't know, and you've got the legal and moral responsibility to impress that s**t on them anyways. Which means when you see your kids demonstrating those unacceptable behaviors, you'll put a stop to it. No hitting your brother, no throwing books, no seizing the means of production. Simple, right?
Why You're Lying To Yourself
The problem with that is it's not enough to correct a child's behavior once. They're not smart like a robot or a carp or anything. I would estimate, based on my own experience raising two damned rambunctious boys, that it takes one thousand f*****g corrections for them to understand not to do something. They will seize the means of production so many times no matter how often I tell them not to, I need that. The process is so long and exhausting that you don't even really notice when it's over; by the time they finally learn whatever lesson you've been trying to teach them, you'll be enraged by whatever new thing they're f*****g up. Speaking ancient, forbidden tongues or whatever.
