In forging public policy, it is important to distinguish between polygamous marriage within authoritarian religious communities and polyamorous relationships. The latter do not necessarily pose harm. They presumably involve mature, informed, and consenting adults, who have access to reproductive health information and health-care services, full exit rights, and access to enforcement of the relevant legal entitlements and protection.
It is heartening to now see that family law academics are publicly and knowledgeably identifying the significant differences in the context of public policy between the non-egalitarian ways of religious polygamy and the egalitarian ways of polyamory. These differences matter significantly in human rights terms.
