Let me make it simpler for you; the opinions of children are irrelevant to me. I do not care for morality and its subjectiveness, I only care for adults objective decisions. Why? Because children are weak, therefore we adults can enforce our rules on them. What are the purpose of these rules is for us to decide. If the purpose is children's welfare then we can objectively create, amend or abolish the rules using science. Children's opinions are irrelevant.
