Haidt and Lukianoff offer a much clearer and stronger case for how social media and other influences are harming youth in their book "The Coddling of the American Mind: How Good Intentions and Bad Ideas Are Setting Up a Generation for Failure".
In my mind they intellectually coddle users by providing an echo chamber where they can spout their ideas to a group chosen specifically of people who will agree with them.
The coddling argument is imho just weak. It is "the kids these days have it too easy" argument to devalue their positions without really arguing with them.
