As someone who came of age and attended college in the 2000's, the current left is virtually unrecognizable. On any given policy question there were a dozen different proposed solutions being debated at any one time. Left leaning publications weren't all clones of each other and often had distinctive ideologies. One could actually disagree on different aspects of an issue without being ostracized (Obama actually supported civil unions as an alternative to gay marriage in 2008).

Something happened once the Soviet Union dissolved.  There was always a counter culture which was of the left, and it always had radical voices in it, but with the loss of the last great power rival of the 20th century, it almost did, as was said at the time, end history in a way.  Or a version of it.  It stopped being about competition in the here and now, and what will we do, to having the luxury and comfort of being able to look back at what we did.  Over time, we've become more and more obsessed by it.  As bad as the CCP is, it's just not the Soviet Union in terms of grabbing your attention.  

Then there's 9/11, almost just one full decade after the fall of the Soviets, that showed the US was not untouchable.  It was a singular moment, with unique circumstances, but it rattled us deeply.  Pearl Harbor happened before that, but that was done when there were multiple expanding empires around the world.  Legit empires.  Like the ones you read about in history books.  That was not the context of the world at the time of 9/11.

Then the final blow in the trilogy coming in 2016...when, yup, Harambe was taken away.
