I understand your perspective, but I'm going to disagree with what I think you mean, which is that /only/ parents should be responsible for their kids, and that nobody else should have to do anything at all for them. I know that's not exactly what you said, but given the context it's what I am going to argue against.

Kids are a normal part of our society. We were all kids at one point. Our lives were all made better by reasonable accomodations that others made for our safety and wellbeing. If the outside world is only designed for adults, then there is an impossible burden on parents to raise children.

I think we can and often do make reasonable accomodations for kids. Like checking IDs at the bar or checking heights before letting people on a rollercoaster.

What that level of responsibility is for websites, I'm not sure. But it's not zero.
