This Article takes seriously the substantive due process and equal protection arguments that support plural marriage (being able to marry more than one person at the same time). While numerous scholars have written about same-sex marriage, few of them have had much to say about marriages among three or more individuals. As progressive, successful, and important as the Marriage Equality Movement has been, it focuses on same-sex marriage at the expense of other possible kinds of marriages that may be equally worthwhile. The vast majority of Americans still do not discuss plural marriage openly and fairly, as if the topic were taboo. One of the goals of this Article is to convince readers that marriage in the future could be a much more diverse institution that does a better job of meeting individual needs. After all, one size may not fit all. Unfortunately, too often, scholars reduce plural marriage to the exploitation of women and the abuse of children. This approach makes it too easy to dismiss the possibility that a plural marriage might work better than the alternatives for at least some individuals in some circumstances
