 Focusing on the case of David Reimer who was medically reassigned from male to female after a botched circumcision, Butler reexamines the theory of performativity that she originally explored in "Gender Trouble" (1990).David, then renamed as a girl- Brenda, rediscovers his masculinity and goes on to live his life as a male again.While many of Butler's books are intended for a highly academic audience, "Undoing Gender" reaches out to a much broader readership.
