Language has redefined black as bad; from the times in ancient Egypt where black was associated with fertility and prosperity to now where it is seen as morbid, evil, and depressing. No matter what we call ourselves, if we are not liked, that dislike will transform the language.
Black is fabulous. Kandee made an excellent point in saying that it has been redefined. Structuralists harp on and on about signifiers and the importance of language etc. The fact of the matter for me is that someone else made that decision to make black -ve, like Kandee asserted. I will not take that definition because it is not me, end of story. Black people need to hijack all these old means and take them for positive.
