This chapter, distilled from a long book on the topic, analyzes the 1,850 year tradition of Western laws against polygamy and the growing constitutional and cultural pressures to reform these laws today. I show how the traditional Western cases against polygamy and same-sex unions used strikingly different arguments drawn from the Bible, nature, rights, harm, and symbolism. I conclude that, because these arguments are so different, Western nations can responsibly hold the line against polygamy, even if they choose to accept same-sex marriage and its accompanying norms of sexual liberty, domestic autonomy, equality, and nondiscrimination.
