Polygamy may be next but I will bet it will also coincide with an attack on age of consent laws. Polygamists are also known for disregarding morality in regard to age of consent already and I honestly believe that has been the major goal behind the sexual rights movement anyway.
The case about polygamy is this:
1) Repeal age of consent, or at least lower it slightly
2) Argue that there are milder forms, or exceptions to the rule that it’s inherently pedophilic (the cast of Sister Wives).
3) Argue that we should be left alone, or that the laws are hypocritical considering that cohabitation is tolerated. Again, another political agenda was famous for saying that the state has no business in the bedrooms of the nation, and now they want about everyone to know. Again, on the flip side, it’s good to know plenty of religious leaders are getting more on the case of people who cohabit without marriage, at least without the church sacrament, that is. They should keep working at this, and hopefully we can make something else that is not right less encouraging.
4) Argue that there is no harm. However, if these communities are really all so isolated against people who wouldn’t practice religious polygamy, there’s bills to foot regarding inbred kids, not to mention possible tax cheats, and other issues. Amongst homosexuality, AIDS, STDs, drug use and more are already highly disproportional to their proportion in the population.
