 Another issue raised by such a reform proposal is how to delimit the relationships entitled to such recognition. Recall the new natural law charge that liberalism entails an objectionable “plasticicty” regarding marriage (3.2.1). One question is whether recognition should be extended to polygamous or polyamorous relationships. Some defenders of same-sex marriage hold that their arguments do not entail recognizing polygamy, due to its oppressive effects on women (Wedgwood 1999). However, some monogamous marriages are also oppressive (March 2011), and egalitarian polygamous or polyamorous relationships, such as a group of three women or three men, exist (Emens 2004). Thus, oppressiveness does not cleanly distinguish monogamous from polygamous relationships. Brooks has sought to show that polygamy is distinctively structurally inegalitarian as one party (usually the husband) can determine who will join the marriage, whereas wives cannot (Brooks 2009). However, this overlooks various possible configurations—if a polygamous “sister wife,” for instance, has the legal right to marry outside the existing marriage, there is no structural inequality (Strauss 2012). Most fundamentally, some authors have urged that a politically liberal state should not prescribe the arrangements in which its competent adult members seek love, sex, and intimacy, so long as they are compatible with justice (Calhoun 2005, March 2011). Some philosophers have argued that polygamists and polyamorous people are unjustly excluded from the benefits of marriage, and that legal recognition of plural marriage - or small groups of friends – can preserve equality (Brake 2012, 2014, Den Otter 2015, Shrage 2016). Finally, the history of racialized stigmatization of polygamy gives reason to consider whether anti-polygamous intuitions rest on just foundations (Denike 2010).
