In my limited experience, it seems to me that the most racial segment of our society are the Blacks. They even discriminate within their group, if one of their group is dark black, he is considered a pariah.
This was noticed in Black-sploitation films years ago.
The badder a villain was the Blacker he was.
It’s the lighter-skinned blacks that are the most racist. They also tend to look down upon darker blacks...but if you ever notice, they are usually the ones making the most noise against Whitey....as if they need to prove they’re really black, and not a mix.
