Systemic racism is both a theoretical concept and a reality. As a theory, it is premised on the research-supported claim that the United States was founded as a racist society, that racism is thus embedded in all social institutions, structures, and social relations within our society. Rooted in a racist foundation, systemic racism today is composed of intersecting, overlapping, and codependent racist institutions, policies, practices, ideas, and behaviors that give an unjust amount of resources, rights, and power to white people while denying them to people of color.
