Hipster-hate strikes me as just another thinly veiled form of bullying, and it's interesting to see how readily internet nerds - the people who are disproportionately to have been bullied in the past - engage in it.

"The reaction, then, had nothing to do with hipsters. It was a hatred of people that need to stand out for standing-out's sake.
