Raphael Cohen-Almagor's article "Hate in the Classroom: Free Expression, Holocaust Denial, and Liberal Education" (2008) calls for sanctions on those K-12 public school teachers whose deployment of "hate speech"--and/or associations with others who deploy it--creates a "poisoned environment" in the classroom. While stating his belief in the role of free expression as "a fundamental right and value in democracies," Cohen-Almagor nevertheless believes that hate speech "causes immediate mental and emotional stress" and perhaps even "psychological harm" to those it targets and so has no place in the public school system, which should be guided by liberal educational principles. He illustrates his argument by reference to the cases of three Canadian teachers, each of whom has had his teaching certificate revoked, is politically on the far right, and is directly or indirectly associated with Holocaust denial. In this rejoinder, the author focuses on Cohen-Almagor's contention that public school teachers should be fired if their out-of-classroom utterances or associations cross liberal and contractual requirements. The author argues that what Cohen-Almagor presents is an illiberal educational argument in the service of putatively liberal educational principles. (Contains 25 notes.)
