R. Derek Black’s coming out story is complicated. As a child, Black came out to the world as a white nationalist on the syndicated daytime talk program “The Jenny Jones Show” in 1999. Then, while trying to hide their white nationalist credentials as a college student roughly a decade later, Black was outed in a student-run online forum. In 2013, Black came out yet again: In an article published by the Southern Poverty Law Center, Black condemned white supremacy and their famous family’s ideology and came out as an antiracist. Now, in the memoir “The Klansman’s Son,” the 35-year-old child of former Ku Klux Klan leader Don Black and a close family friend of the notorious former KKK grand wizard David Duke is coming out as transgender.
