Among the black community, they identify those blacks who were born and raised in Africa,
who have the deepest, dark skin pigmentation as :" Blue-blacks" (with a slight blueish hue to the skin).
The "Blue-blacks" generally and historically intermarried within their own tribal group in Africa due to geographic isolation.
Then you have an identified "mixed-mulatto" black group
Then you have an identified "light skin" black group, which suggests common inter-racial and mixed marriages .
As I recall, it was Mrs. Robinson, Michelle's mother who was opposed to her daughter's marriage to Barack Obama because he wasn't "black enough".
That sounds awfully racist to me, and not dependent on his personality or character.
Usually, when a black person says ‘That person is not ‘black enough’ for me to easily accept them.’ The way
Grandma Robinson did, they are using their own skin tone as the measure.
So if Barrack was lighter in skin tone that Michelle or her mother’s side of the family, then he didn’t meet the ‘standard’ of what they thought acceptable. “He didn’t walk the ‘struggle’ like I did. He got off easy!”
In my opinion, the worst definition of this demographic was "Blue-gum, turn-row, cotton-patch n*****s".
