"The folks at UCLA gave me a list of the topics we're allowed to talk about tonight," joked Dave Rubin, creator and host of "The Rubin Report" and moderator of this panel on current threats to free speech on college campuses.

Free speech is a bedrock principle throughout the Western world, but increasingly it is being challenged — on college campuses, among intellectuals and in politics — in the name of preventing "hate" speech or offensive speech, or protecting allegedly "marginalized" groups. Why is this happening, and what does it mean for the future of free speech?

In this panel discussion, sponsored by the Ayn Rand Institute and the UCLA chapter of the Federalist Society, three leading figures in this field address the current threats to this fundamental right in the United States and the free world: Flemming Rose, author of "The Tyranny of Silence: How One Cartoon Ignited a Global Debate on the Future of Free Speech" and former editor at the Danish newspaper Jyllands-Posten; Steve Simpson, Director of Legal Studies, Ayn Rand Institute, and editor of "Defending Free Speech," and Dave Rubin.

This event was recorded live at the UCLA Law Building on the campus of the University of California, Los Angeles, on Wednesday, February 1, 2017.
