Consider the case of someone i will call Mr. Oreo. Mr. Oreo cannot even think of passing, being quite dark with clearly black African features and with known black ancestry. But he is unhappy with his racial resignation, so he fills in "white" on bureaucratic forms, identifies himself as white, and rejects black culture. Will these gestures make him white?
Suppose individuals such as Mr. Oreo whose bodies are not . . . naturally white make us of [Plastic surgery techniques or genetic engineering to make it possible to transform one's skin, hair, and facial features so that one looks completely white] and then go on to assimilate as above. [Would they be white or just look white?] . . . Compare another kind of physical transformation, that of bodily physique and strength. if a machine were invented (Call this the Schwartzenegger Machine) that could transform 98-pound weakling into massively muscled superman capable of pressing hundreds of pounds without the tedium of years of special diets and weight training, would we say that the person only looked strong but had not really become strong? Obviously not: His new body, new physique, new strength are real. So What is the difference?
