This month, the Supreme Court reviewed a trifecta of free speech cases that has government and civil libertarians alike on edge. While each of the cases raises an insular issue, they collectively run across the waterfront of free speech controversies facing this country.

For some of us, what was most chilling from oral arguments were the sentiments voiced by justices on the left of the court, particularly Justice Ketanji Brown Jackson. The court may now be reflecting the shift among liberal scholars and politicians away from freedom of speech and in favor of greater government speech regulation.

In my forthcoming book, "The Indispensable Right: Free Speech in an Age of Rage," I explore the evolution of free speech in the United States, including the failure of the Supreme Court to protect free speech during periods of political unrest. Although a new revolutionary view of free speech emerged at the founding of the republic, it was quickly lost due to the regressive views of the federal courts over centuries of conflicted decisions.

We are now living through one of the most anti-free speech periods in our history. On our campuses, law professors are leading a movement to limit free speech under the pretext of combating hate speech or disinformation. A dangerous triumvirate has formed as government, corporate, and academic interests have aligned to push limitations of free expression.

That triumvirate is now before the Supreme Court, which is looking at cases where government officials targeted critics, dissenting websites, and revenue sources.

What was disconcerting was to hear many of those same voices from our campuses echo this week on the court itself.

In Murthy v. Missouri, the court is considering a massive censorship system coordinated by federal agencies and social media companies. This effort was ramped up under President Joe Biden, who is arguably the most anti-free speech........
