A study examined the sentiment and impact of different types, channels, and forms of aggression against the Arab-American community during the Gulf Crisis. Data were selected from entries in the 1990 Anti-Arab Discrimination and Hate Crimes Log of the American-Arab Anti-Discrimination (ADC) National Office. Results show that there were 129 acts of aggression vented against Arab-Americans during the first four months of the Gulf Crisis. Offensive language, threats, and ethnic slurs were used most, through the channels of print, face-to face encounters and radio respectively. The primary form of face-to-face aggression was verbal, although even physical attacks against Arab students occurred on American college campuses after the United States bombed Libya. Stereotyping not only has a harmful effect on the Arab community, but can cause psychological damage to Arab youngsters, who must cope with students who ridicule them in school. The study concluded that negative stereotyping plays a large role in shaping or reinforcing bigotry, and that additional scholarly research is called for.
