Derek Black was raised to take over the white nationalist movement in the United States. His father, Don Black, was a former Grand Wizard in the Ku Klux Klan and started Stormfront, the internet’s first white supremacist website—Derek built the kids’ page. His godfather, David Duke, was also his mentor. Racist hatred, though often wrapped up in respectability, was all Derek knew. Then, while in college in 2013, Derek publicly renounced white nationalism and apologized for his actions and the suffering that he had caused. The majority of his family stopped speaking to him, and he disappeared into academia, convinced that he had done so much harm that there was no place for him in public life. But in 2016, as he watched the rise of Donald Trump, he immediately recognized what he was hearing—and he knew that he couldn’t stay silent.
