In his devastating new book The Madness of Crowds, Douglas Murray examines the twenty-first century's most divisive issues: sexuality, gender, technology and race. He reveals the astonishing new culture wars playing out in our workplaces, universities, schools and homes in the names of social justice, identity politics and `intersectionality'.

We are living through a postmodern era in which the grand narratives of religion and political ideology have collapsed. In their place have emerged a crusading desire to right perceived wrongs and a weaponization of identity, both accelerated by the new forms of social and news media. Narrow sets of interests now dominate the agenda as society becomes more and more tribal - and, as Murray shows, the casualties are mounting.
