When I was in that age bracket it was not having a Myspace that was socially isolating. A few years ago (I&#x27;d estimate 2009 to early 2013) it was Facebook within the later half. Having just clicked the WSJ link. The graph shows &quot;Fall 2012&quot; is the fall off of Facebook which lines up with my memory.<p>Either way, my broader point was &quot;social media being &#x27;optional&#x27; doesn&#x27;t really mean it is &#x27;optional&#x27;&quot;. You can opt out - but there is a tradeoff that not everyone is willing to make.<p>As for indoctrination - I&#x27;m far more concerned with 18-25 year olds who have the ability to vote being indoctrinated into a certain mindset than 13-17 year olds. (E: You know what, on a second visit to my post both are equally bad as the 13-17 will be able to vote &quot;soon&quot; too.)<p>ps: Twitter has a similar issue. They suppress and attempt to censor trending hashtags (preventing them from autocompleting) that go against their political standings.
