I have almost never hear of racism being specific to whiteness. The caste system is not racist because it's perpetrated along caste lines, which exist even within the same ethnic groups. Ethnic hatred between groups, for example, in Africa is still racism. Even though from a Western racial lens they'd all be categorized under the umbrella of "Black", it's racism because the involved parties see each other as a race apart.
