"Did he strike a nerve?"

A bit. I wish someone would compare the number of 'hipsters' to the number of recent immigrants whose ethnicities don't match the historic neighborhoods that they moved into. I think that they would find that those recent immigrants had much more to do with changing New York over the past few decades than hipsters. Of course, not a whole lot of people have the balls to do that because the fear being called racist, insensitive, etc.
