White racist extremist gang members, while few in terms of their representation in the total United States gang member population, cause a disproportionate number of problems. Their gangs, composed of only whites or Caucasians, are most closely associated by the public with hate crimes motivated by racial bias and racial/ethnic prejudice. The sample for this study consisted of 82 hard core white racist extremists from the Aryan Brotherhood, Aryan Nation, and Aryan Youth Movements, Ku Klux Klan, neo-nazis, skinhead groups, white power groups, and motorcycle gangs. The profile of the white racist extremist gang member presented in this article includes data in the following categories: (1) school and education; (2) sexual activity; (3) family life background; (4) religious background; (5) drug-related activities; (6) reasons for joining a gang; and (7) reasons for quitting a gang. The article also includes profiles of gang organization and behavior, and of how gang members adjust to life in a correctional institution. References, notes
