Further to my exchange with TimT in the comments, I thought I’d post this 2009 lecture by David Horowitz.
Part 1: An academic bill of rights. Parts 2 through 8 are below. If you can, watch the whole thing.
Part 2: Activism versus education.
Part 3: “I’m in the astrophysics department so they can’t hurt me.”
Part 4: Rap as scholarship; feminist umbrage.
Part 5: Ward Churchill, “little Eichmanns” and terrorist cred.
Part 6: William Ayers (terrorist cred part 2); the Duke lacrosse saga.
Part 7: Non-reciprocal tolerance; Che Guevara “studies.”
Part 8: Flat Earth freedom; counterfactual history; the thug veto.
