Calling children “radically disempowered” is almost an understatement. Pretty much from the moment they’re born, children are subject to a world that treats them as much like property as like people. Children grow up in a world with no voice. There are countless rules and regulations controlling their daily lives, and they have absolutely no say in any of those rules. They are subject to the whims of the people around them- people who may or may not have their best interests in mind. Children have no privacy and no right to a fair trial when an adult (parent) accuses the child of wrong doing. Their entire lives are at the whims of people who control what clothes they wear, whether they have a roof over their heads, whether they even eat.
Being a child isn’t easy. Very little in your life is under your own control, and you’re also subject to your body’s whims. Children are still growing and developing, and they don’t always even understand how or why they feel certain ways. They may not know why they’re tired or cranky at any particular moment. And, as someone else pointed out, even if they do know, they’re still subject to other people’s whims. An adult who isn’t feeling well can call in sick and avoid interacting with other people, in many cases. Children don’t have that option.
And this is the group that some people have decided that they hate?
Some excuse the hating as just hyperbole. Well if we all excused our 'hates' as hyperbole then we'd be nowhere. "That [insert race here] cashier jipped me $5! I hate them!" "One time my sister dated a [insert religion here] guy and he totally tried to run her life. Stay away from them!"
