Jessica Krug, 38, is actually a white Jewish woman from Kansas City but told staff and students at the US university were she teaches that her heritage was black and Latina.
She revealed the truth in an article published on the website Medium.
Krug, who lectures at George Washington University in Washington DC, wrote: “To an escalating degree over my adult life, I have eschewed my lived experience as a white Jewish child in suburban Kansas City under various assumed identities within a Blackness that I had no right to claim – first North African Blackness, then US rooted Blackness, then Caribbean rooted Bronx Blackness.
“I have built my life on a violent anti-Black lie.” Her deception continued throughout the furore caused by US “black” activist Rachel Dolezal being exposed by her parents as white in 2015.
Krug acknowledged she, too, had no right to claim a black identity, saying that “doing so is the very epitome of violence, of thievery and appropriation, of the myriad ways in which non-Black people continue to use and abuse Black identities and cultures”. She added: “I am not a culture vulture. I am a culture leech.”
Krug blamed mental health issues and childhood trauma, although she added this was not an excuse.
