This is an excellent article on why polygamy and gay marriage rights cannot be compared. Some of the points made are;
- This competitive, zero-sum dynamic sets off a competition among high-status men to hoard marriage opportunities, which leaves lower-status men out in the cold. Those men, denied access to life’s most stabilizing and civilizing institution, are unfairly disadvantaged and often turn to behaviors like crime and violence. The situation is not good for women, either, because it places them in competition with other wives and can reduce them all to satellites of the man.
- a 2012 study, for example, that discovered “significantly higher levels of rape, kidnapping, murder, assault robbery and fraud in polygynous cultures.”
- monogamous marriage “results in significant improvements in child welfare, including lower rates of child neglect, abuse, accidental death, homicide and intra-household conflict.” And: “by shifting male efforts from seeking wives to paternal investment, institutionalized monogamy increases long-term planning, economic productivity, savings and child investment.”
- societies become inherently unstable when effective sex ratios reach something like 120 males to 100 females, such that a sixth of men are surplus commodities in the marriage market. That’s not a big number: “The United States as a whole would reach that ratio if, for example, 5 percent of men took two wives, 3 percent took three wives, and 2 percent took four wives—numbers that are quite imaginable, if polygamy were legal for a while.”Read more: http://www.politico.com/magazine/story/2015/06/polygamy-not-next-gay-marriage-119614#ixzz3soGSqQPK
