How about you parent better and prevent your kids by educating them against the dangers of said things?Limit their time online and what they can do? Why should democracy be at stake and people's freedoms, just so you can get away with not parenting.

Yes, in theory that's correct but show me a kid that never did something against the will of their parents. If something is forbidden it's something worth investigating. Furthermore there will always be another kid with a phone to share watching anything online. The traditional solution has been forbidding with punishments when the kids get caught breaking the rules.

Ok, so what do you do when your child visits a friends house and they have unrestricted access to the internet?
