It is not necessary to dump our kids into institutions to be raised by their peers. It is necessary that you don't make decisions for other peoples kids.

Whether you legalize social media or not (or smoking, or drinking, or riding in a car without a seatbelt), that's making a decision for other people's kids. Choosing parental liberty is still choosing.

I sympathize with the libertarian impulse but for me, protecting my kids from other parents' poor decisions comes first.
