The definition of a marriage is the union of a man and a woman but not multiple partners. This therefore implies that inclusion of several partners redefines the meaning of marriage, as people have known it throughout human history. Although certain individuals may have the financial capacity to take care of their multiple partners, this act is simply immoral. For instance, in the case of polygyny, the woman is undermined. This implies that women are given low status in the society because they are owned in a similar way as properties. This is morally wrong and can only be avoided if polygyny is illegal. In the case of polyandry, it would be very difficult for a single woman to play the roles of a wife to several husbands (Díez MInguela, 2011). In addition, there would be too many children and chores to take care of for the woman. This is not to mention the possibility of conflict eruption in the family if the husbands do not agree on certain aspects.
Polyandry continues to oppress against women. This is because in most instances, especially in the developing world, women are usually forced to get married since their parents view them as a waste of money if allowed to attend school. The issue gets worse when they are forced to get married to elderly men at tender ages (Tertilt, 2003). From this perspective, women are deprived of the right to choose what they wish to do. This adds to oppression against the female population and can be avoided if polyandry is illegal. If it were prohibited, women would have the chance to attend school and participate in developing their countries. Additionally, this practice goes against the teachings of the Holy Scriptures. This is because besides requiring a man to be committed to one wife, the Holy Scriptures also requires both to be faithful to each other.
