On March 30, 2010, officials at the University of Wyoming, citing "security threats" and "controversy," canceled two talks I was invited to give in early April, one a public lecture entitled "Trudge Toward Freedom: Moral Commitment and Ethical Action," and the other, a talk to faculty and graduate students called "Teaching and Research in the Public Interest: Solidarity and Identity." I'd been invited in August, 2009, but one week before I was to travel to Laramie, I was told I had been "disinvited."
