At its most untamed, fandom poisons. It contorts logic into blind worship. It bites and stings and slices anything in its path. It gnaws on tendon meat, a wide ruby-red smile, unkind and uncaring about its target, its prey. Fandom crushes whole and curdles into cancel culture. It’s all mob instincts. It’s collective brute force. It’s “Stand on our side or get whacked,” Soprano style. In the most extreme cases online, fandom asks: What won’t you do for the person or group or thing you love the most?
