I am a white woman. I am standing beside a black woman. We are facing a group of white people who are seated in front of us. We are in their workplace, and have been hired by their employer to lead them in a dialogue about race. The room is filled with tension and charged with hostility. I have just presented a definition of racism that includes the acknowledgment that whites hold social and institutional power over people of color. A white man is pounding his fist on the table.
