One of the things I found useful to do in class is to ask students to find examples of concepts talked about in class or in the textbook and to bring these into class. Here's one on stereotyping and indiscrimination. It comes from Senator Joseph Lieberman (reported in the New York Times, 7/16/06, p. 20): "The Irish tend not to be fair-weather friends," Mr. Lieberman said. "They're with you all the way." I find such comments incredible, especially when made for public consumption by a leading politician.
