Posobiec’s book, written with Joshua Lisec, is titled “Unhumans: The Secret History of Communist Revolutions (and How to Crush Them).”

Vance wrote an “editorial review,” commonly known as a blurb, praising the book. It’s a small but fresh example of how conspiracy theorists have become massively influential among Republicans.

“In the past, communists marched in the streets waving red flags. Today, they march through HR, college campuses, and courtrooms to wage lawfare against good, honest people,” Vance wrote. “In ‘Unhumans,’ Jack Posobiec and Joshua Lisec reveal their plans and show us what to do to fight back.”
