Wut? If they’re using the internet they should be aware of that stuff. That’s what ‘just be kids’ means these days. Just being a kid isn’t a static state of being.
So then they shouldn’t use the internet. I’m not going to fill my kids mind with all the dangers in the world when all they should be thinking about when they’re 8 is academics, friends and personal pursuits and achievements.
It's no longer safe for children to be unsupervised on the internet.
