When David Horowitz named the "101 most dangerous academics in America," in The Professors, a book in 2006, Bettina Aptheker was among those featured. A professor of feminist studies at the University of California at Santa Cruz, Aptheker was critiqued this way in the book:
The concepts of academic freedom are much debated, and it's clear that not everyone who uses the term means the same thing. A new book, For the Common Good: Principles of American Academic Freedom (Yale University Press), traces the history of academic freedom and its definitions in the United States. The authors are two law professors: Matthew W. Finkin of the University of Illinois at Urbana-Champaign and Robert C. Post of Yale University.
