In this episode, Dominic Green talks to Heather Mac Donald, a scholar at the Manhattan Institute. She is the author of The Diversity Delusion: How Race and Gender Pandering Corrupt the University and Undermine Our Culture, a scathing and accurate critique of just about everything that’s gone wrong with American higher education. When she was invited to speak at Claremont McKenna College in California, student groups organised on Facebook to “shut down” the “notorious white supremacist racist Heather Mac Donald.” When she got to campus, she was moved directly to what would otherwise be called a “safe space” for her own protection. With a police escort, and more than two hundred black-clad protestors banging on the windows, she had to livestream her speech from a vacant room.
