For the first time in human history, children, having unfettered access to the internet, are confronted with myriad ideas. Some, nay most, that they probably disagree with, that don't make them feel especially good, or are even perhaps unsettling. Truly, they have become uncoddled.
Rather than framing this as a bad thing, we should take it as a sign that it's working. We shouldn't then say, "Social media is making them feel worse" - that's exactly the mentality of the coddled mind. We should be implementing policy that increases internet and in particular social media use for children. After all, being confronted with uncomfortable ideas, especially ones that make you feel worse, in fact makes you stronger.
