"Ok, I got the denotative meaning, but in terms of ordinary usage how does the definition apply, how would I use 'Identity' to decribe myself as an American of unknown African ancestry?
I thought would be good to start with what is my defintion of identity. With that done, I would not tell you how to describe yourself. You should do that. I would describe myself as having an identity that of African American-American.
"Hey, come to think of it, you mentioned 'color' and 'race', are they not synonymous in America?" --- Our Empowerment
Could be, I guess. The default standard for color is "white" and "non-white." The default standard for race is Caucasian and non-Caucasian. They are not the same thing although they include/reference the same people. The benchmark target of the color standard in "black." The benchmark target of the race standard is Negro. Again, they are not quite the same thing. And in this case, there is a preferred target even within the broad objective in both cases, namely Americans of unknown African ancestry.
