An 11-month Title IX investigation found Professor Ronell, described by a colleague as “one of the very few philosopher-stars of this world,” responsible for sexual harassment, both physical and verbal, to the extent that her behavior was “sufficiently pervasive to alter the terms and conditions of Mr. Reitman’s learning environment.” The university has suspended Professor Ronell for the coming academic year.

In the Title IX final report, excerpts of which were obtained by The New York Times, Mr. Reitman said that she had sexually harassed him for three years, and shared dozens of emails in which she referred to him as “my most adored one,” “Sweet cuddly Baby,” “cock-er spaniel,” and “my astounding and beautiful Nimrod.”

Coming in the middle of the #MeToo movement’s reckoning over sexual misconduct, it raised a challenge for feminists — how to respond when one of their own behaved badly. And the response has roiled a corner of academia.
