Forget sex or politics or religion, loneliness is the subject that clears out a room.

Coupland’s line suggests that, despite the reputation of sex, politics, and religion as “dangerous” conversation, loneliness is even more socially destabilizing. It is not merely controversial; it is contagious in the sense that it makes listeners uncomfortable, implicated, or helpless—unsure whether to offer sympathy, solutions, or silence. The quote also points to a cultural taboo: modern life may be saturated with talk about identity, desire, and belief, yet it often lacks a shared language for isolation. By calling loneliness the topic that “clears out a room,” Coupland highlights how communities can fail precisely where human need is most basic: the need to be seen and accompanied.
