About this book

Dr. Gad Saad, host of the YouTube show "The SAAD Truth," argues that the West's commitment to freedom, reason, and liberalism faces threats from viral ideological forces in contemporary society. He describes an epidemic of what he calls "idea pathogens" spreading through Western culture and eroding common sense. Saad, a professor at Concordia University, examines various concerning thought patterns, belief systems, and attitudes that have contributed to political correctness. He discusses what is happening in progressive spaces, why these trends warrant attention, and what steps are necessary to counter the spread of what he views as dangerous thinking. The book addresses the serious consequences of these developments and calls for intervention.
