Minstrelsy thrives on TikTok, but the phenomenon goes back a long way. The earliest American iterations emerged in the 1840s as a form of entertainment and endured for more than a century.

The musical acts, comedy sketches, and dances relied on stock characters, like Sambo and Zip Coon, to parade Blackness as laughably uneducated or as a target of humiliation.But the mask of Blackness cannot be worn without consequences. It can't be worn as a joke without reaching into some deep cultural and historical ugliness, without opening a wound of abuse and humiliation.

“The Black man in America is the most copied man on this planet,” Mooney said. “Everybody wanna be a nigga but nobody wanna be a nigga.”
