How do you know that the majority of youths are just sitting in their rooms jacking off to porn and play video games all day? You just assume they do, cause you're describing your own experiences from an environment you're part of.
Isn't it enough obvious. It's not completely doomed and I clearly said majority. It's not an assumption as if it would be a ten years ago, now it's obvious reality. And you better have a plot of stopping it rather than arguining if it's true or not.
