text: First of all, we have no school sponsored sports at our school. Legally, you can't ban kids from school not to attend other types of sponsored sports. Unless you are their legal parent or guardian, then this surely won't work. Majority of parents will most likely disagree with this plan, whether its football, swimming, tennis, etc. and so will the rest of the school. You don't have the right to decide what they do and don't do if it's outside of the school's grasp.
