Racism, classism and sexism are a part of the air we breathe every day. Even if we could uproot them completely today, when we awake tomorrow, they will be at our doorstep as regular as the newspaper. Farmers must weed their fields every day, and we must uproot prejudice just as regularly. The day farmers come to believe they have finished their work is the day they begin to lose their fields to the weeds. And those who say they have eliminated their own prejudice have, in their heads, nests filled with vulture eggs waiting to hatch.
