The New War on Free Speech: Why Power Turns Everyone Into a Censor

Free speech was supposed to be the great settled achievement of liberal democracy. Then came social media, cancel culture, campus speech battles, hate-speech laws, authoritarian tech control, and a new era of governments pressuring platforms from every direction. Michael Shermer speaks with free speech scholar Jacob Mchangama about why speech protections are weakening around the world—not only in dictatorships, but inside democracies. Their conversation moves from the First Amendment and January 6 to hate speech laws in Europe, Section 230, Elon Musk and X, online anonymity, social media bans for minors, and the enormous promise and danger of AI. Mchangama argues that censorship is less a left-wing or right-wing impulse than a human one: once people gain power, the urge to silence enemies becomes almost irresistible. The real test of free speech is not whether we defend ideas we like, but whether we resist using state power against speech we despise. Jacob Mchangama is the founder and executive director of The Future of Free Speech and a research professor at Vanderbilt University. His new book is The Future of Free Speech: Reversing the Global Decline of Democracy's Most Essential Freedom.
