Jonathan Rauch: Allowing free speech

American author Jonathan Rauch argues free speech and robust criticism should be encouraged and defended, even when it's racist, sexist or causes hurt. A gay, Jewish writer and thinker Rauch admits free speech can do harm, but argues minorities are better off in a society where free speech is embraced. Rauch has been visiting NZ at the invitation of the Free Speech Union discussing the necessity of academic freedom. He's a senior fellow in the Governance Studies programme at the Brookings Institute, the author of eight books and many articles on public policy, culture, government, and LGBT rights.
