A racial equality officer, gay rights, and anti-rape activist at Oxford University is resigning her positions after admitting she engaged in “not consensual” sex while at a student conference.

Annie Teriba appears to have sterling credentials as an activist. She edited the journal No Heterox**, targeted at Oxford’s “queer and trans*” communities, was a member of the black students’ committee for the U.K.’s National Union of Students (NUS), and worked as a racial equality officer at Oxford. Recently, she has helped lead a campaign to tear down a campus statue of Cecil Rhodes, whose estate funds the prestigious Rhodes Scholarship. She once moved another student to tears by attacking an Arabian Nights-themed party as racist, and she once wrote an editorial decrying the “endemic problem of rape culture” on campus.

But now, it turns out that Teriba may have been the cause of so-called “rape culture,” not its victim. Recently, Teriba announced she is resigning all her positions and stepping away from her political campaigns. She offered an explanation on Facebook that was later deleted, but not before it was copied by the student publication Cherwell. Besides explaining her departure, the post also serves as a peculiar act of political immolation.
