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.
