Robin DiAngelo spends more time than your average white female Seattleite thinking about race. DiAngelo, who lives in Greenwood, teaches classes on social justice at the University of Washington’s School of Social Work and travels around the state giving diversity workshops. She laughs about how much the topic suffuses her life: When she’s not conducting workshops, she attends talks about race, panels about race, events focusing on race. Her focus makes sense. She’s the mind behind white fragility, the idea that white people in the United States often grow up without having to talk or think about race and fail to build up the tolerance needed for discussions of any depth on the topic. When confronted with this understandable weakness, they often lash out or withdraw—the fragility in question.
