Why do parents have the right to decide anything about a child's upbringing, or their moral, social, political and spiritual education? Young children are trusting when it comes to their parents, and may even believe falsehoods if their parents are the ones who are repeating these falsehoods. So why do we recognize a unilateral right for parents to teach their children whatever they want, and to withhold whatever information from their children that they deem appropriate? Why do we let parents pull their children out of sex ed class, or teach them a religion as a unilateral source of truth?
Shouldn't parents have responsabilities, instead of rights? Surely shaping a child's mind, personality and outlook is not the "reward" parents get for feeding and clothing them! Is this just a practical issue ("There's nobody in a better position to take care of the kids, and there's no way we can stop people from teaching them whatever they want")? Or is there some fundamental moral reason parents have the right to do what they want with (or to) their children's minds?
