"Radical Son" by David Horowitz recounts the author's journey from being a prominent left-wing activist to a conservative thinker. Raised in a Communist family, Horowitz immerses himself in the radical counterculture of the 1960s and becomes a fervent advocate for social justice.

He details his experiences as a writer and editor for the New Left magazine "Ramparts" and his subsequent disillusionment with its radical agenda. As he dives further into his intellectual transformation, he reflects on the impact of his upbringing on his political beliefs and challenges the prevailing narratives that perpetuate hatred and division.

Exploring the intricacies of identity politics and its detrimental effects on society, the author uncovers the dangers of radical ideologies and the erosion of individual freedoms. Drawing on his own compelling personal narrative, Horowitz exposes the destructive consequences of utopian idealism and offers a thought-provoking analysis of the true nature of totalitarian movements.

In "Radical Son," David Horowitz provides a candid account of his ideological shift, presenting a critical examination of the politics of the left, while championing the value of personal freedom, individual responsibilities, and the pursuit of truth.
