Let’s get one thing out of the way: Everyone is a fan of something.
It could be a band, or a football club, or a particular celebrity that you’re a fan of. You could be a fan of your kid, or your cat, or chocolate covered donuts. We are all different, but we all need something to be excited about.
There is, however, a difference between being a fan and BEING A FAN. There exists a group of people who take being a fan to a new level, which can make things rather problematic for the peaceful coexistence of fans of different orientation.
