What that article effectively says is "more and more, kids are turning into assholes while their parents alleviate guilt by giving kids whatever they can to redirect confrontation." Sure, that's an industrial problem alright, but also a very short-sighted analysis of it.
Civility itself, or the adoption of norms that you and I hold dear, fundamentally come into question here; that reflects in lots of places. You can pin that sentiment on any community with a perceived low barrier for entry and self-identification, especially during adolescence these days.
Put simply, while very well articulated, that piece is wearing blinders. Any time you think you've spotted an endemic problem in a specific community, you have to look outside of it, and that was left out of this.
