Author and columnist Douglas Murray discusses his book “The Madness of Crowds: Gender, Race and Identity”. As Murray describes in his book, “the interpretation of the world through the lens of ‘social justice,’ ‘identity group politics’ and ‘intersectionalism’ . . . is the most audacious and comprehensive effort since the end of the Cold War at creating a new ideology.” Also discussed are European politics, Boris Johnson’s tenure as UK prime minister, and a sobering look at American politics from the perspective of a very sharp observer.
