I want to know the answer to the following question:
How are people defined as "black" or "white"?
All the background I'm provided with is that "The US racial or ethnic classification "black" refers to people with all possible kinds of skin pigmentation, from the darkest through to the very lightest skin colors, including albinos, if they are believed by others to have West African ancestry (in any discernible percentage), or to exhibit cultural traits associated with being "African American".". Is that enough to answer the question?
Answer: no
