Philosophers at St. Olaf College and Carleton College objected when a local pub, The Contented Cow, scheduled conspiracy theorist and Holocaust denier Jim Fetzer to give
one four in a series of “CowTalks” on assorted political issues. Alan Rubenstein (Carleton) withdrew from a debate with Fetzer (see update) at the Cow, and St. Olaf professors Gordon Marino, Danny Muñoz-Hutchinson, and Michael Fuerstein emailed the owner of the pub to complain. The owner sent the emails to Fetzer, who posted them online. Predictably, this led to the professors receiving threats and hate mail. According to an article in the Manitou Messenger, “the threats directed at the Carleton professor were serious enough that the FBI became involved. On Jan. 27, the Contented Cow canceled the talks, citing pressure from the community.” (via Cherie Braden)
