The Barney hate started years ago with teenagers and adults. The source of the hate was not necessarily due to the show itself but how people perceived it. A 2017 New York Times article reported that adults and teens grew increasingly irritated by Barney’s voice and exaggerated chirpiness. While constant happiness is a weird reason to hate a show, the Barney Hate Camp seemed to think otherwise. However, things quickly escalated beyond mere hate.
In the early 2000s, some teenagers reportedly beat up a man wearing a Barney costume at a shopping mall. In the years that followed, anti-Barney humor became a thing. For instance, a 2003 article by The Guardian referenced a culture where the US military seemed to believe that the Barney ‘I Love You’ song could break Iraqi prisoners during interrogation. As hilarious as this may sound, the US soldiers interviewed in the article strongly believed that the song was that horrific.
More disturbingly, someone created a website (jihad.net) to prompt the Jihad to destroy Barney, and to encourage/support Barney hate. Get this, the website is still being maintained today. That's how intense the hate was (or still is).
Till today, there are still memes encouraging Barney hate on the internet.
