I want to know the answer to the following question:
What defines "blackness"?
All the background I'm provided with is that "Blackness can be contrasted with "acting white", where black Americans are said to behave with assumed characteristics of stereotypical white Americans with regard to fashion, dialect, taste in music, and possibly, from the perspective of a significant number of black youth, academic achievement.". Is that enough to answer the question?
Answer: no
