Prejudice and discrimination

Herbert George Wells (21 September 1866 – 13 August 1946) was an English writer. Prolific in many genres, he wrote dozens of novels, short stories, and works of social commentary, history, satire, biography and autobiography. His work also included two books on recreational war games. Wells is now best remembered for his science fiction novels and is often called the "father of science fiction", along with Jules Verne and the publisher Hugo Gernsback.

White supremacy is the belief that white people are superior to those of other races and thus should dominate them. The belief favors the maintenance and defense of any power and privilege held by white people. White supremacy has roots in the now-discredited doctrine of scientific racism and was a key justification for European colonialism.

John Bordley Rawls (February 21, 1921 – November 24, 2002) was an American moral and political philosopher in the liberal tradition. Rawls received both the Schock Prize for Logic and Philosophy and the National Humanities Medal in 1999, the latter presented by President Bill Clinton, in recognition of how Rawls' work "helped a whole generation of learned Americans revive their faith in democracy itself."

In social psychology, a stereotype is a generalized belief about a particular category of people. It is an expectation that people might have about every person of a particular group. The type of expectation can vary; it can be, for example, an expectation about the group's personality, preferences, appearance or ability. Stereotypes are often overgeneralized, inaccurate, and resistant to new information. A stereotype does not necessarily need to be a negative assumption. They may be positive, neutral, or negative.

Hate speech is a term with varied meaning and has no single, consistent definition. It is defined by the Cambridge Dictionary as "public speech that expresses hate or encourages violence towards a person or group based on something such as race, religion, sex, or sexual orientation". The Encyclopedia of the American Constitution states that hate speech is "usually thought to include communications of animosity or disparagement of an individual or a group on account of a group characteristic such as race, color, national origin, sex, disability, religion, or sexual orientation". There is no single definition of what constitutes "hate" or "disparagement". Legal definitions of hate speech vary from country to country.

A barbarian is a person or tribe of people that is perceived to be primitive, savage and warlike. Many cultures have referred to other cultures as barbarians, sometimes out of misunderstanding and sometimes out of prejudice.

A pejorative word, phrase, slur, or derogatory term is a word or grammatical form expressing a negative or disrespectful connotation, a low opinion, or a lack of respect toward someone or something. It is also used to express criticism, hostility, or disregard. Sometimes, a term is regarded as pejorative in some social or ethnic groups but not in others or may be originally pejorative but later adopt a non-pejorative sense (or vice versa) in some or all contexts.

The Great Gypsy Round-up (Spanish: Gran Redada de Gitanos), also known as the general imprisonment of the Gypsies (prisión general de gitanos), was a raid authorized and organized by the Spanish Monarchy that led to the arrest of most Roma in the region and the genocide of 12,000 Romani people. Although a majority were released after a few months, many others spent several years imprisoned and subject to forced labor. The raid was approved by the King Ferdinand VI of Spain, and organized by the Marquis of Ensenada, and set in motion simultaneously across Spain on 30 July 1749.
