Ana, it would be an insult because it would be a denial of what is true would it not? Surely a person with black or very dark skin is just that, little point and rather silly to proclaim ' I am white if one is not white, just as silly as proclaiming i am black if one has white skin, so different is one is speaking of one's nationality, a friend of mine had a father who was white and from Holland, his mother was black and born in the UK, he is black because his skin is not white, he is British because he was born in the UK, it!s not a case of choice , one is the colour of the skin one is born with
