Re "Natural law dictates 2-gender society," Forum, Jan. 14:
The idea that natural law dictates that marriage is only between a man and a woman has a several holes in it. The first is that the natural order provides two types of "marriage." Most pack animals are polygamous in nature.
The second would be serial monogamy. Most birds, fish and reptiles fall into this category. Male and female mate for one season then move on.
