Bestselling author and journalist Douglas Murray's brand-new book "The Madness of Crowds: Gender, Race, and Identity," (which goes on sale today) examines gender, sexuality, race, and technology to reveal the new culture wars playing out in homes, workplaces, schools, and universities. Murray argues we're living in a postmodern era where the grand narratives of religious and political ideology have collapsed to be replaced by a crusading desire to right perceived wrongs and a weaponization of personal identity, all in the name of social justice, identity politics, and intersectionality. The book has already generated some controversy, with many praising Murray's work while others have dismissed it as a "rightwing diatribe." William Davies of The Guardian even accused Murray of being "blind to oppression." Murray joins Gormley now to discuss his book.
