Wars cause the number of women to greatly exceed the number of men. In a monogamous society these women, left without husbands or support, resort to prostitution, illicit relationships with married men resulting in illegitimate children with no responsibility on the part of the father, or lonely sisterhood or widowhood. Easy birth control and easy legal abortion has opened the door of illicit sex to woman and she has been lured into the so-called sexual revolution. But she is still the one who suffers the trauma of abortion and the side effects of the birth control methods. Taking aside the plagues of venereal disease, herpes and AIDS, the male continues to enjoy himself free of worry.
Men are the ones protected by monogamy while women continue to be victims of men's desires.
Polygamy is very much opposed by the male dominated society because it would force men to face up to responsibility and fidelity. It would force them to take responsibility for their polygamous inclinations and would protect and provide for women and children. Among all the polygamous societies in history there were none which limited the number of wives. All of the relationships were unrestricted. In Islam, the regulations concerning polygamy limit the number of wives a man can have while making him responsible for all of the women involved.
