I like to think of it this way:
There are black people who are culturally black, and there are black people who are physically black. Most black people are in touch with black culture.
At a certain point Michael jackson stopped looking black. He was still very much plugged into his black heritage and defined himself as a black man.
Mariah carey looks like a white woman with a tan, but continuously puts herself in black spaces and isn't ashamed of her black heritage.
Clarence Thomas is darker than midnight, but he wants nothing to do with black liberation and he probably has date nights listening to Bing Crosby with his HAWG.
Candace Owen's is technically black but the moment anyone who isn't brimming with sellout energy encounters her they realize "this isn't one of us" it's like when a cat looks at a realistic looking stuffed animal. It smells the stuffed animal and it's eyes tell it that it's looking at another cat, but it's other senses and instincts recognizes something is off. It hisses and swats away the stuffed animal. When you're looking at a c00n you instinctively know "this isn't one of us"
