Not giving your kids access to the internet at all is insane. You're setting them up for failure by not actively teaching them how to navigate the Internet and what bs to look out for. Anyone that does this is just trying to indoctrinate their kid and prevent them from being exposed to any other ideas. The ego on parents that think they know enough to entirely prepare their kids for the world is ridiculous. Especially these days. You're just setting them up to be behind when they're older and they'll resent you while they struggle to catch up.
