I cannot. If I was able to provide a coherent explanation of this single issue, I'd have a doctorate material at my hands, ready to be published.
Titanium: you thought my sarcastic exclamation as in "yes, you should DEFINITELY brainwash your child" was how I actually feel? Whoops.
As I said - there can be people out there who actually believe that, even if you're not among them yourself. The whole idea behind trying to raise a child by forcing them to do some things and forbidding others is based on the "obedience is intelligence" assumption commonly applied to dogs (as in: a "smart" dog is the one you can easily teach tricks). It's quite obvious that the only way a child can grow up to be a reasonable adult is through having a mind of its own, thinking instead of blindly obeying.
But I also disagree with your statement on people beings slaves to their brains, though I find a glimmer of hope in the use of "most" instead of "all".
The value I find most precious in all of universe is "freedom" or "liberty". To assume that the world itself enslaves me and provides with merely an elaborate illusion of freedom would be "heresy". Neither I nor anyone else can prove this wrong, just as it is impossible to conclusively prove it right.
Call it faith - I believe we aren't set on rails, I believe things can be different than they will be. I believe in choice and possibility.
But that's a bit offtopic. I also believe in mercy and humility, as I've already stated, so I think this should've been solved by a calm conversation. Waging a war against a child isn't going to accomplish anything, other than lead even deeper in the spiral of mutual hatred.
Coercion begets rebellion.
Edit:
Wow, look what Google gave me...
