The most fascinating proposition of the book is that a previously marginalized heritage-multiracial-is the source of the next historically significant social identity. After tracing identity from its origins in kinship to its most recent in race, the author argues that the opposition to a multiracial identity, hypo-descent-more commonly known as the one-drop rule-is the last socially accepted form of racism, but that this is ultimately unconstitutional. And so once this is demonstrated-and the author quite convincingly does so-multiracial identity will find social acceptance, allowing a large portion of our population to realize its fullest potential.
