I think a commonly overlooked part of this coddling is that it teaches kids and teenagers to be afraid of things they don't need to be afraid of, which is exactly how they end up as "puriteens". I remember as a child being terrified to change the channel on the tv because I had ended up with the impression that seeing even seconds of an R rated movie or tv show would give me nightmares. And then as a tween every time I saw swearing I felt sick to my stomach because I had been taught such a thing is bad and harmful. I think I would have suffered less if I hadn't been raised with everyone around me acting like mature media was so bad. By the time I was a teenager I had figured out this was bunk, but understandably a lot of people don't. By making this whole system worse and stronger you have teens who have been told that seeing explicit or dark media Will Harm Them, and so they act in ways that would be appropriate if it really was the info-hazard it's implied to be.
