This house would legalise polygamy.

So cutting to the chase, in this round I limit my arguments to three major assertions, as my hands have been shackled by PRO's imposed word limit. =Discord in family life=Emotionally, it is possible to have feelings for more than one person at a time. Pragmatically though, loving more than one person is unmanageable and difficult to do. Ergo, marriage assures emotional and sexual exclusivity between two partners. Polygamy involves having multiple relationships. Love is not a rational feeling, it is an emotional drive and is usually enhanced by certain stimulating circumstances and incidents that occur between individuals. It is more than obvious that in the long run, polygamy will cause a person to have more attachments emotionally to one person, than the others involved in the whole polygamic relationship. Thus, the person in question would end up weighing one(or more) relationship(s) higher in valuableness than the others. This promotes ego, and creates negative feelings like jealousy and hatred towards the said relationship(s), in the hearts of other parties involved. A succesful marriage is one that lasts till the end. Polygamy has a greater likelihood of sparking emotional disharmony and discord in the relationships for the said reasons and can conclude in divorces or in extreme cases heinous acts like cheating and murder. =Creates a pool of Unmarried Low-Status men=It is natural that if polygamy is legalized, a rise in the number of un-married men would be seen. But what would be the magnitude of such a rise? Dr. Henrich explains the cold mathematics of polygyny:[1]This illustration reveals the underlying arithmetic that can result from polygamy. Imagine a society of 40 adults, 20 males and 20 females. Suppose those 20 males vary from the unemployed high-school drop outs to CEOs, or billionaires. Let's assume that the twelve men with the highest status marry 12 of the 20 women in monogamous marriages. Then, the top five men (25% of the population) all take a second wife, and the top two (10%) take a third wife. Finally, the top guy takes a fourth wife. This means that of all marriages, 58% are monogamous. Only men in the to 10% of status or wealth married more than two women. The most wives anyone has is four. The degree of polygynous marriage is not extreme in cross-cultural perspective but it creates a pool of unmarried men equal to 40% of the male population who are incentivized to take substantial risks so they can eventually participate in the mating and marriage market. This pattern is consistent with what we would expect from an evolutionary approach to humans, and with what is known empirically about male strategies. [1]So we get a society were 40% of the total male population are left un-married and desperate for a relationship(remember that they didn't 'choose' to be un-married). Thus, with the high neccessary demand for females, occurences of infidelity will steeply increase, destroying the peacefulness and harmony, that would have been seen, in a 'normal' marital relationship. Also it has been scientifically proven that marriage civilizes men. [1]Research shows marriage makes men much less likely to commit crimes such as murder, robbery and rape. One such study showed that marriage reduced the likelihood of committing a crime by 35%. This study was particularly compelling as it did not simply compare the criminality of married and unmarried men, but used longitudinal data to track boys from a reform school from age 17 to 70. In this study, crime rates not only decreased when those men were married, but increased when they divorced or were widowed. Other studies are consistent in showing the association between monogamous marriage and decreased male criminality. [1]Ergo, we have excellent reasons to conclude that polygamy will ensue an increase in crime rates and violence in the society. =Poor Parenthood=Multiple relationships imply multiple families. A marital relationship is sophisticated and requires great care and attention for it to be succesful. The group that would feel the greatest burden from a polygamic marriage would be, the children born from such a relationship. Since there are several families to take care of, it is obvious that there would be a steep decrease in parental investment. [2] The underlying theory is that since married men would remain perennially in the marriage market, high-status men could choose to invest their resources in acquiring more wives rather than investing in their children. Similarly, the pool of unmarried men would be forced to invest their resources in attempting to improve their status so as to improve their chances of finding a bride. [2]Even though the above may seem less intuitive it is basically, the truth. I will be backing this asserstion in R3 if PRO may contest it, but beacause of the word limit, I'm incapable of doing so now . Over to you,PRO. Sources:1: . http://is.gd...2: . http://is.gd...
