Discrimination on the basis of such grounds as subcultural preference (Punks, Hippies?, Mods vs. Rockers?) is also common.
Discrimination spans the spectrum from exceedingly mild, such as slow or unhelpful retail service, through racial and ethnic slurs, denial of jobs or housing, to hate crimes and genocide.
Many governments have attempted to control discrimination through [civil rights]? legislation, while in other regimes such as apartheid in South Africa, insitutionalized racial segregation in the USA from the [Civil War]? through the 1960's, the "Jewish problem" in Nazi Germany, or re-education camps in some communist countries, discrimination has been formalized and government-supported.
