“Intending a parallel with terms like racism and sexism, DePaulo says singlism is “the stigmatizing of adults who are single [and] includes negative stereotyping of singles and discrimination against singles.” In her 2006 book, Singled Out, she argues that the complexities of modern life, and the fragility of the institution of marriage, have inspired an unprecedented glorification of coupling. (Laura Kipnis, the author of Against Love, has called this “the tyranny of two.”) This marriage myth—“matrimania,” DePaulo calls it—proclaims that the only route to happiness is finding and keeping one all-purpose, all-important partner who can meet our every emotional and social need. Those who don’t have this are pitied. Those who don’t want it are seen as threatening. Singlism, therefore, “serves to maintain cultural beliefs about marriage by derogating those whose lives challenge those beliefs.”
