"Another young man radicalized by the Lorax"—Netizens react as Luigi Mangione GoodReads and Letterboxd accounts go viral online

Luigi Mangione — the suspected killer of UnitedHealthcare CEO Brian Thompson - was arrested on Monday, December 9 at a McDonald’s in Pennsylvania's Altoona, as reported by BBC. The 26-year-old had a gun, bullets, a silencer, four fake IDs, a US passport, and a manifesto with him at the time of arrest.

Soon after the news broke, netizens began digging into Luigi's digital footprint, with multiple people highlighting his supposed Goodreads and Letterboxd accounts.

Internet sleuths shared screenshots purportedly containing Luigi’s reading and watchlist. They claimed the 26-year-old's list contained a large number of nonfiction books, replete with anti-establishment and similar ideologies.

One interesting find was The Lorax — a children's book by Dr. Seuss. The book is mainly a fable depicting environmental issues such as climate change.

The story encourages one to do their part to protect the environment and preserve nature. An X user claimed Luigi left five stars on The Lorax on Goodreads.

"Unless someone like you cares a whole awful lot, nothing is going to get better. It's not", another person shared a screenshot claiming his last-liked quote was from this very book.

Luigi's supposed interest in such books sparked different reactions online. One X user seemingly critiqued how Luigi was likely influenced by the book:

Another Letterboxd screenshot depicting Luigi Mangione's alleged favorite movies includes the 2012 film adaptation of Dr. Seuss' book The Lorax, Ariana Grande and Cynthia Erivo-starred Wicked, M. Night Shyamalan's 2024 thriller Trap starring Josh Hartnett, and Charli XCX's 2021 documentary Alone Together.

Netizens shared their reactions to Luigi's supposed Letterboxd and Goodreads footprint.

"Bros a brat and an assassin", joked one X user.

"Broadway escape before confinement", another chimed in.

"TRAP?!?? One of the worst movies ever made in the history of earth", one X user commented.

"Bro has horrible movie taste if Trap was on his favorites list", resonated another.

However, X Community Notes claimed the list did not belong to Luigi Mangione, but rather to the OP.

"A man of culture", said another.

"He’s a militant centrist reddit normie and this is arguably good", one commented.

Luigi Mangione allegedly reviewed Theodore John Kaczynski's manifesto on Goodreads

Four stars were left as a rating on Theodore John Kaczynski aka the Unabomber's Industrial Society and Its Future on Goodreads, by what is suspected to be Luigi Mangione's account. In a lengthy review, the 26-year-old seemingly held Kaczynski's predictions about modern society in great value.

According to the official website of the United States Government, Kaczynski left home to live a reclusive life in the mountains of Montana in the late 1960s. He was a mathematician turned terrorist who planted bombs that killed three individuals and injured about 23 people between 1978 and 1955.

Kaczynski's manifesto — an essay where he explained how he viewed modern society and the motives behind his act - mainly criticized leftist ideologies.

Luigi Mangione, in his supposed review, wrote:

"He was a violent individual — rightfully imprisoned — who maimed innocent people. While these actions tend to be characterized as those of a crazy luddite, however, they are more accurately seen as those of an extreme political revolutionary."

Luigi seemingly resonated with Kaczynski's belief that peaceful protest would not lead to fruitful results. He added:

"When all other forms of communication fail, violence is necessary to survive."

Luigi Mangione called Kaczynski's act "war and revolution", asserting it wasn't "terrorism".
