A Pedagogical Purpose for the N-Word?

Ethical Educator

Scenario:

A superintendent of 15 years teaches education law at a private university. When discussing employment law in his course, which covers discrimination under the Civil Rights Act of 1964, he considers it vital to explain the groundbreaking significance of the legislation by referencing widespread discrimination against all types of minority groups. To highlight the resistance to the law by legislators in the South, he wishes to quote Sen. Strom Thurmond, who uses the N-word in one of his public speeches as a vocal opponent. May he, as a white professor, use the actual word in class for pedagogical purposes or should he adopt a watered-down version?
