Genocide is the intentional action to destroy a people—usually defined as an ethnic, national, racial, or religious group—in whole or in part. It is the most severe manifestation of intergroup hostility and prejudice. Sociologically, it represents the total breakdown of social cohesion and the ultimate failure of intergroup relations, where one group uses state power or organized violence to eliminate the existence of another group entirely.

Ageism refers to stereotyping, prejudice, and discrimination against people on the basis of their age. Sociologists and researchers typically measure the impact or intensity of such discriminatory practices using the term 'severity'. While other terms like gravity or seriousness might be used colloquially, 'severity' is the standard academic descriptor for the degree of harm or prejudice experienced by the target group.

De jure segregation refers to the separation of groups that is mandated, authorized, or supported by official government legislation or legal systems. This is distinct from de facto segregation, which occurs as a result of social practices, economic factors, or individual choices rather than explicit legal requirements.

The contact hypothesis suggests that interpersonal interaction between members of different groups under appropriate conditions can reduce prejudice and conflict. By working together toward common goals, individuals often develop a more nuanced understanding of one another, thereby diminishing stereotypes and fostering mutual respect. This social psychological concept is widely used in sociology to explain how diverse groups can achieve greater social cohesion through direct, positive engagement in professional or communal settings.

Arab Americans often encounter both individual prejudice and systemic racism. Prejudice refers to negative attitudes or beliefs held about a group, while racism involves the institutional or individual exercise of power to disadvantage that group. Both phenomena frequently intersect in the experiences of minority populations, leading to social marginalization and discrimination in various public and private spheres.

Prejudice is a preconceived opinion or attitude, typically characterized by aversion or hostility, directed toward individuals based solely on their membership in a particular group. It is a cognitive and emotional state that exists independently of actual behavior and often relies on stereotypes to generalize traits to all members of that group.

Executive Order 9066 was signed by President Franklin D. Roosevelt on February 19, 1942. This order authorized the Secretary of War to prescribe military areas from which any or all persons could be excluded, which ultimately led to the forced relocation and incarceration of approximately 120,000 people of Japanese ancestry, most of whom were U.S. citizens, during World War II.
