COMMENTARY MAGAZINE (March 14, 2025):
Late last year, when Luigi Mangione was arrested and charged with the murder of United Healthcare CEO Brian Thompson, something unexpected happened: A lot of people praised him for his actions, elevating Mangione to the status of secular saint for gunning down a man in cold blood. Both on social-media platforms, where he was hailed as a folk hero, and in person outside the New York City courthouse where dozens if not hundreds of supporters waved “Free Luigi” signs, a disturbingly large number of people seemed to be in agreement with Mangione’s claim, in the three-page manifesto found among his belongings, that “frankly, these parasites simply had it coming.”
Mangione’s views aren’t simply run-of-the-mill anti-capitalist rantings. They are grounded in part in the principles of the so-called Rationalist movement. Like many Rationalist (also called Gray Tribe) enthusiasts, Mangione is from a wealthy family, has an advanced degree, and has worked in the tech industry. He shares with the Gray Tribe an obsession with AI and some of ideas that the progression of artificial intelligence has brought to the fore.

Similarly, a culture that embraces the idea that anything is fluid—even one’s own physical body or biological sex or even one’s reality—has a hard time making the case for limits. What comes to take the place of that case is an understanding of the world that says a man can become a hero for fatally shooting someone he doesn’t even know on a New York City street corner. Right now, it may go by the name of Rationalism, but it’s something older and deeper and more terrifying.
