Diversity is not merely difference but differences that arise out of commonality, such as the humanity we all share. Justice implies equality in treatment, privilege, opportunity, or other arenas. Social justice has a connotation of what society ought to do or what society is doing to ensure just treatment of its members. Of course, these concepts require greater precision when used and are prone to misunderstanding and manipulation in contemporary usage. This work aims to clarify terminology used in popular vernacular and expose some of the nuances that we typically don't consider but profoundly impact our thinking, speech, and actions.
