I want to know the answer to the following question:
Why is it bad that a category is merely socially constructed?
All the background I'm provided with is that "He argues that while forensic anthropologists can determine that a skeletal remain comes from a person with ancestors in a specific region of Africa, categorizing that skeletal as being "black" is a socially constructed category that is only meaningful in the particular context of the United States, and which is not itself scientifically valid.". Is that enough to answer the question?
Answer: yes
