A simplified description of the legal definition of discrimination is when a person is treated disfavourably or when a person's dignity is violated.
To treat a person or particular group of people differently, especially in a worse way from the way in which you treat other people, because of their race, gender, sexuality, etc.: be discriminated against She felt she had been discriminated against because of her age.
Discrimination is the unfair or prejudicial treatment of people and groups based on characteristics such as race, gender, age, or sexual orientation.
Discrimination is an action or practice that excludes, disadvantages, or merely differentiates between individuals or groups of individuals on the basis of some ascribed or perceived trait, although the definition itself is subject to substantial debate.
Moral philosophers have defined discrimination using a moralized definition. Under this approach, discrimination is defined as acts, practices, or policies that wrongfully impose a relative disadvantage or deprivation on persons based on their membership in a salient social group.
Noun. 1. an act or instance of discriminating. 2. treatment or consideration of, or making a distinction in favor of or against, a person or thing based on the group, class, or category to which that person or thing belongs rather than on individual merit.
