John Moretta is a seasoned historian with a Ph.D. from Rice University and extensive teaching experience at Central College, Houston Community College, and the University of Houston. Dr. Moretta returns to provide an in-depth analysis of McCarthyism—its origins, its influence on American society at its height, and the ways it continues to resonate in modern times. We delve into the fear-driven environment of the Red Scare, exploring how it shaped public opinion, government policies, and cultural norms during the mid-20th century. Dr. Moretta also discusses the lasting implications of McCarthyism, from its impact on civil liberties to its role in shaping contemporary political rhetoric and attitudes toward dissent.
