The best evidence that "inter-racial" sex is "acceptable" is absence of
the adjective "inter-racial." The ONLY reason the term is used--in fact,
the only reason any racial designations are used--is to identify the
person(s) so described as members of a subordinate or dominant group (or
some layer between these extremes) in a racially hierarchical society.
No racial hierarchy... no need for adjectives of color.
