Perhaps. I'd think it would depend a great deal on whether or not the original stereotype was intended to be positive or negative. Consider the character of Tarzan. In Burroughs' original telling, he was certainly a racial/ethnic stereotype - a 'white'/English boy, raised from infancy by great apes, who taught himself to read and who somehow acquired superior moral standards in the process - even though his only human examples were a very brutish tribe of African natives. This has been retold many times in the movies and TV, and the character of the Africans has evolved, but Tarzan himself remains much the same. Or perhaps I missed the thrust of your question.
