At Yale University, a professor who sparked protests after dismissing concerns about culturally offensive Halloween costumes has resigned. The controversy began in October, when Yale’s administration sent an email reminding students to respect each other’s cultures on Halloween and to avoid wearing offensive or appropriative costumes. In response, professor Erika Christakis sent an email pushing back against the advice, writing: “Is there no room anymore for a child or young person to be a little bit obnoxious… a little bit inappropriate or provocative or, yes, offensive?” Her email sparked protests and came amid other instances of racism on campus, including a woman of color reportedly being denied entry to a fraternity party because she is not white. On Monday, a statement issued by Yale said Christakis had voluntarily decided not to teach in the future at Yale University.
