For the second time this academic year, black students at Stanford Law School are condemning the use of a racial slur by faculty in the classroom.

Last week, professor Michael McConnell—a former federal appellate judge and co-chair of Facebook’s new content moderation oversight board—read a quote attributed to Patrick Henry that contained the “N-word” in his class on the creation of the Constitution. That incident comes just seven months after a Stanford history professor was criticized by students for using the same epithet during a guest lecture in a torts class at the law school.
