The unilateral subjugation of one individual or group by a more powerful individual or group, using physical, psychological, social or economic threats or force, and frequently using an explicit ideology to sanction the oppression. Refers also to the injustices suffered by marginalized groups in their everyday interactions with members of the dominant group. The marginalized groups usually lack avenues to express reaction to disrespect, inequality, injustice and lack of response to their situation by individuals and institutions that can make improvements.
