This high school unit on prejudice encountered by minority groups begins with contradictory descriptions of the character of American Democracy and raises the question, "Is American democracy intrinsically tolerant?" Then, students are invited to examine a number of specific episodes reflecting the treatment of various types of minority groups. A final brief selection from Gordon Allport's "The Nature of Prejudice" suggests the sociological factors that re-enforce prejudice, after which students are asked if Allport's generalizations apply to American society.
