There are no successful polygamous cultures in the world. All polygamy destabilizes the entire culture.
Polyamorists, who (so far) define themselves by “love” rather than marriage, have been arguing the merits of their lifestyle and their rights for some years now, and the movement will hold its fifth international conference at the University of California, Berkeley, in February.
According to a chatty mailout from Saturnia Regna to “polylegal” groups, the International Conference on the Future of Monogamy and Nonmonogamy (official name) will focus on academic presentations but there will also be workshops and sideshows catering for interests ranging from jealousy management and STDs, through folklore, to BDSM.
What is completely missing is the destructiveness of uninvolved fractured fathering on most if not all of the children
The science will, no doubt, include studies on how well children are doing in households with more than two “parents”, where jealousy is always an issue, threatening the stability of the household and the security of the children. Perhaps it will also tell us the rates of STDs and complications among polyamorists, and rates of change in household composition.
Meanwhile, watch out for media stories about happy polyamorist “families” and a history of marriage which makes “consensual nonmonogamy” look almost superior to the one man, one woman and their own children model.
