Shadism

Shadism is a form of skin tone bias that identifies groups and individuals on the basis of degree of skin pigmentation.

It is an evaluation of people that minutely registers traits such as skin color, hair, and facial features to construct social hierarchies. For example, in the context of social apartheid in Brazil, and elsewhere in Latin America, people with pale skin, tall stature, light eyes, dark and very straight or light and straight or wavy hair, and aquiline noses are considered more beautiful, powerful, influent and good-natured than people of European and Middle Eastern descent with other phenotypes, and those are of greater status than lower and middle-class people of Asian descent in social hierarchy, which also gives preference to multiracials (Pardos, mestizos, etc.) whose features more closely touches the idealized Northern and Western Europeans in comparison to those whose facial features, hair texture and skin color more resemble the Africans, or whose facial features and stature more resemble Amerindians, the latter associated with savagery, uneducation and superstitions.

Shadism is closely related to 'colorism', an associated practice that is the manifestation of an internalized, colonial-induced racial self-hatred.

Endogamy

Endogamy is the practice of marrying within a social group, rejecting others based solely on culture as being unsuitable for marriage or other close personal relationships. Cultures that practice endogamy require marriage between specified social groups, classes, or ethnicities. A Danish endogamist, for example, would require that a marriage be only with another Dane.

gingerism

Antiziganism

Antiziganism (pronounced /æntaɪˈzigənɪzm/) or Anti-Romanyism is hostility, prejudice or racism directed at the Roma people, commonly called Gypsies.

The root zigan is the basis of the word for the Roma people in many European languages. In most of those languages, the pronunciation is similar to the Hungarian cigány (pronounced [ˈtsiɡaːɲ]). The Roma — who have often been stereotyped as thieves, tramps, con men and fortune tellers — have been subject to various forms of discrimination throughout history.

Due in part to their semi-nomadic lifestyle and differences in language and culture, there has been a great deal of mutual distrust between the Roma and the more settled indigenous inhabitants of the areas to which the Roma migrated. This distrust has persisted even though Roma who migrated into Europe often converted to Christianity, and those who arrived in the Middle East became Muslims.
