You say that like it's a good thing, when a lot of people believe that the final frontier of liberation is within the family - from domestic violence to the dismantling of anti-LGBT attitudes.

And, just to return to the original topic, the original article does not actually mention children. Even if we constrained social networks to those over 18 (they're currently supposed to be constrained to over-13), it wouldn't put much of a dent in the big problems. It's not (just) kids that are sharing antisemitic memes or fake news about immigrants. The dysfunctional politics of social media is an adult problem.
