Elizabeth Marquardt outlines the three avenues from which group marriage will come : the fringes of the left, from the darkest corners of the fundamentalist right, and from the laboratories of fertility clinics and hard scientists around the world.
The debate about legal recognition of polyamorous relationships is already well underway. A major report issued in 2001 by the Law Commission of Canada asked whether marriages should be “limited to two people.” Its conclusion: probably not. A British law professor wrote in an Oxford-published textbook that the idea that marriage meaning two people is a “traditional” and perhaps outdated way of thinking. Elizabeth Emens of the University of Chicago Law School published a substantial legal defense of polyamory in a legal journal. She suggested that “we view this historical moment, when same-sex couples begin to enter the institution of marriage, as a unique opportunity to question the mandate of compulsory monogamy.”
Mainstream cultural leaders have also hinted at or actively campaigned for polyamory. Roger Rubin, former vice-president of the National Council on Family Relations—one of the main organizations for family therapists and scholars in the United States—believes the debate about same-sex marriage has “set the stage for broader discussion over which relationships should be legally recognized.” The Alternatives to Marriage Project, whose leaders are featured by national news organizations in stories on cohabitation and same-sex marriage, includes polyamory among its important “hot topics” for advocacy. The Unitarian Universalists for Polyamorous Awareness hope to make their faith tradition the first to recognize and bless polyamorous relationships. Meanwhile, a July 2009 Newsweek story estimates that there are more than half a million “open polyamorous families” living in America. Nearly every major city in the U.S. has a polyamory social group of some kind.
