Speaking as a lighter-skinned conscious idren, I have never felt "rejected", ever in my life, by darker-skinned [Black African] people, based on my lighter shade of skin color or the fact that my biological and familial father is categorized as white.
This includes my bredren's wife from "G.T." as we call the Land of Many Waters, who described me once as 'white'. She didn't try to chop my head off with a cutlass like how our national hero Cuffy (Kofi) did to the Dutch backra dem in Berbice in 1763. She did not ignore me when I asked her a question. She treated me perfectly "civilly" [as in "civilization"... people who treat one another with "civililty", although that is not the usual definition, the usual definition involves building bigger buildings, having an elaborate hierarchical social structure, "inventing" "writing", and having the capacity to kill more people than your "uncivilized" neighbour has.]
All she did was [as I found out later through her husband] refer to me as 'white.'
When I found that out, I did not feel 'rejected'. I'd been called a lot of things before, such as "nigger", "four-eyes" [Bespectacled People of the World, Unite!], but I'd never been called 'white.' Rather than feel "rejected", I used it as an opportunity to try put myself in someone else's shoes, and get perhaps a brief, vague glimpse of the perspective from which someone could label me as 'white.'
"Ah wish ah had a nice clear-skin chile like dat"- quote from some Black-skinned woman who was out strolling with her baby, while I was passing by walking by with my parents, in Georgetown, Guyana around 1980 or so. I was young but I remember it well and I knew there was something wrong with the comment even at the time.
