I do. I also grew up on 4chan because I didn’t have an involved parent, and I lived in the suburbs where finding friends to just “go outside and play” wasn’t an option. Consuming that content was genuinely hurtful and probably forever altered my psyche. I have the means and knowledge, in technical skill and life experience, to know how these things work, and protect my kids from that. Most people don’t.

Raising children is hard but assuming everyone has to sacrifice their rights so your job is easier means everyone means everyone loses long term.

Or this should be done at point of sale, like we do with all controlled substances.

We don't sell bottles containing alcohol and then expect to filter the alcohol out if the child wants to drink from it. We have two different bottles: alcoholic bottles and non-alcoholic bottles. If you are a child, you cannot purchase the former.

Stop selling unrestricted computing devices to children. Require a person to be 18+ to purchase an unrestricted internet device. Make it clear that unrestricted internet access, like alcohol and nicotine (and the list goes on) is harmful to children. That resolves 90% of the problem.

And lets be fair, the problem isn't the children. Children want what all their peers have. The problem isn't their peers. The problem is the parents. Give the spineless parents a simpler way to say no to their children, and the overall problem goes away.
