Debates over the origins of racism often suffer from a lack of clarity over the term. Many use the term "racism" to refer to more general phenomena, such as xenophobia and ethnocentrism, although scholars attempt to clearly distinguish those phenomena from racism as an ideology or from scientific racism, which has little to do with ordinary xenophobia. Others conflate recent forms of racism with earlier forms of ethnic and national conflict. Notions of race and racism often have played central roles in such ethnic conflicts. Historically, when an adversary is identified as "other" based on notions of race or ethnicity (particularly when "other" is construed to mean "inferior"),"" the means employed by the self-presumed "superior" party to appropriate territory, human chattel, or material wealth often have been more ruthless, more brutal, and less constrained by moral or ethical considerations. According to historian Daniel Richter, Pontiac's Rebellion saw the emergence on both sides of the conflict of "the novel idea that all Native people were 'Indians,' that all Euro-Americans were 'Whites,' and that all on one side must unite to destroy the other. A documentary about Africa: Different but Equal, claimed that racism, in fact, only just recently surfaced—as late as the 1800s, due to the need for a justification for slavery in the Americas.The idea of slavery as an "equal ; opportunity employer"
