By Perpetua CharlesThis year marks the fortieth anniversary of the court decision in Loving v. Virginia that struck down anti-miscegenation laws across the United States. Thanks to this ruling, people across races could legally declare their love for each other through marriage. Sheryll Cashin’s new book, Loving: Interracial Relationships and the Threat to White Supremacy, offers a history of interracial relationships in the United States and looks at how present interracial relationships will shape the future of the country. As I read Loving, I was struck by a short section near the end of the book. Cashin writes that one doesn’t have to marry, date, or adopt a person of another race to experience transformational love or to acquire what she calls cultural dexterity—an enhanced capacity for intimate connections with people outside one’s own tribe. An intimate friendship works just as well. Cashin doesn’t use the word friend lightly, and neither do I.
