How many of these trends are we seeing and how much of a fraction of a fraction do they represent in sum? The article discusses specific declines but doesn't look at data regarding increased incidences of social-media-driven acts of deviance. That's like pointing at the declining use of the saddle while ignoring the rise of the automobile. I guess I should revise my previous hyperbolic statement as I don't know if the deviance is made up for in other ways, I would just have appreciated a broader view.
You're seeing point wise incidents, chosen to generate outrage, and trying to apply them like all kids are doing these things, which per all trends they are not.
Sorry some fraction of people will always be stupid, we shouldn't apply constraints on the many to save the few stupid ones.
