That is my stance on the matter. It existing isn't some grave heresy but how widespread and increasingly marketed to children it has become. Johnny Doe Jr shouldn't be able to watch a video game streamer on YouTube, see a "click my links below" in the description, and be two clicks from hardcore pornography. The dismissal is always that they had to click the links but why are safe-for-kids videos two links from porn to begin with? Once he knows his streamer does that, he will seek it out and whatever site he finds it on, is now exposed to even more.
There's no effort, cost, or knowledge required for a child to end up here. It can all be gained from watching a video on Twitch or Twitter. A child doesn't haven't any idea of self modulation. He will constantly seek this out because it gave him dopamine. Prior to widespread internet porn, there was some cost or effort to all this that made it impractical to get kids completely addicted to this. Parents shouldn't leave their kids with unfettered access to the internet but it doesn't abscond the guy giving crack to kids at the playground because the parents weren't paying enough attention to him.
