'Having the internet' is different to the ubiquitous internet access that kids growing up today are subject to. Twenty years ago you couldn't take out a smart phone and watch porn. You couldn't even readily download porn videos, images perhaps if you were lucky. Even so you were unlikely to have unrestricted access to your own computer with internet access, so watching porn was a special event when the parents were asleep or out. A kid today could pull up porn on their phone right now without a second thought. And it's that 'without a second thought' that is the (slightly) disturbing bit, because it happens before kids develop a proper sense of right and wrong.

If I'm honest and I think back to the playground when I was younger, I am sure my understanding of what's right and wrong would be different (worse in my opinion) than they are today.

On the other-hand I'm in favour of free-speech, but then I also think banning kids from disruptive influences (alcohol, smoking) is also an effective means of keeping kids safe until they can take full responsibility for their actions.
