Passage:

The question of race has caused bloodbaths throughout history, Take the case of the Negro, a negro is someone with black skin who comes from Africa. It is an old-fashioned word and is offensive. Some people used to write that way deliberately. The word ‘nigger’ is also very offensive. The word was later replaced by “coloured” which gave way to “black”, Black is a colour with negative suggestions.
So we have expressionslike ‘black deed’, “black day” and ‘blackmail’. So no wonder the word ‘black’ too assumed unfavourable meanings. (Although in the 1960's the famous slogan ‘Black is beautiful’ was coined, and it did not help). The Blacks of the United States therefore came to be called Afro-Americans. Now, the politically oorrect phrase is African American.
