At least 5-times in the past year, U-S college campuses have been shaken by incidents involving racist e-mail directed at minority students. One ephithet-filled message appeared on computers at Boston College last October. It insulted blacks, latinos and asians and declared Boston College a "white man's school". In the weeks since the e-mail appeared, some white male students at Boston College have been thinking new thoughts about the meaning of race. NPR's Phillip Martin reports.
