A faculty seminar discussing “diversity in the classroom” held at nine of the 10 UC campuses during the 2014-2015 school year came with a worksheet entitled “Tool: Recognizing Microagressions and the Messages They Send.” “Microaggressions are the everyday verbal, nonverbal, and environmental slights, snubs, or insults, whether intentional or unintentional, that communicate hostile, derogatory, or negative messages to target persons based solely upon their marginalized group membership,” states the opening sentence. The ultimate cure for such “hurtful” behavior? Tossing free speech on the ash heap of history.
