A child's associations, location and every action is subject to the will of the adults around them, along with being manipulated into adopting those adults' thoughts and opinions. Children are forced into the institution of parenting through governments which set up property rights over them. Parents' rights is a euphemism for slaveholders' rights. If the child's behavior fulfills your values, you apply an affirming emotion, if the child's behavior deviates from the fulfilment of your values, you apply an antagonistic emotion.
Some parents might say: 'but | can allow children to flourish free from coercement, so that they can become themselves', or something like that. Sure, you might not teach your child religion, but what are you going to do when you realize that your child isn't going to speak your language? Or that it doesn't want to wear clothes? Or violates the cultural system of property rights? And just, in general, isn't abiding by the structure of your society? It's impossible to be an egalitarian parent because you will inevitably coerce your child into behaving in ways which are within the culturally defined parameters. That is the entire purpose of children under any culture. You're not doing your children a favor by bringing them into existence, children exist solely for the propagation of the values of the adults who own them.
