A British Columbian judge ruled that polygamy harms women and society, thus containing the “right to marry” to just two people.
Polygamy, which has been practiced in many places across time and history, has a track record of being associated with certain other social practices. Gay marriage, which was invented ten years ago, has no comparable track record.
In any case, an array of people with culturally powerful credentials were willing to testify against polygamy and to marshall empirical evidence against it.
The judges’ decision, an excellent cheat sheet into the empirical, historical, and social science debate over polygamy in the academy, is here.
Of course it’s being appealed.
