"Race" is still sometimes used within forensic anthropology (when analyzing skeletal remains), biomedical research, and race-based medicine. Brace has criticized this, the practice of forensic anthropologists for using the controversial concept "race" out of convention when they in fact should be talking about regional ancestry. 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.
Why is it bad that a category is merely socially constructed?
is not itself scientifically valid

Bermuda's modern black population contains more than one demographic group. Although the number of residents born in Africa is very small, it has tripled between 2000 and 2010 (this group also includes non-blacks). The majority of blacks in Bermuda can be termed "Bermudian blacks", whose ancestry dates back centuries between the 17th century and the end of slavery in 1834, Bermuda's black population was self-sustaining, with its growth resulting largely from natural expansion. This contrasts to the enslaved blacks of the plantation colonies, who were subjected to conditions so harsh as to drop their birth rate below the death rate, and slaveholders in the United States and the West Indies found it necessary to continue importing more enslaved blacks from Africa until the end of slavery (the same had been true for the Native Americans that the Africans had replaced on the New World plantations). The indigenous populations of many West Indian islands, and much of the South-East of what is now the United States that had survived the 16th- and 17th-century epidemics of European-introduced diseases then became the victims of large-scale slave raiding, with much of the region completely depopulated. When the supply of indigenous slaves ran out, the slaveholders looked to Africa). The ancestry of Bermuda's black population is distinguished from that of the British West Indian black population in two ways: firstly, the higher degree of European and Native American admixture; secondly, the source of the African ancestry.
What term is used to refer to the majority of black people in Bermuda?
Bermudian blacks

 The exta were the entrails of a sacrificed animal, comprising in Cicero's enumeration the gall bladder (fel), liver (iecur), heart (cor), and lungs (pulmones). The exta were exposed for litatio (divine approval) as part of Roman liturgy, but were "read" in the context of the disciplina Etrusca. As a product of Roman sacrifice, the exta and blood are reserved for the gods, while the meat (viscera) is shared among human beings in a communal meal. The exta of bovine victims were usually stewed in a pot (olla or aula), while those of sheep or pigs were grilled on skewers. When the deity's portion was cooked, it was sprinkled with mola salsa (ritually prepared salted flour) and wine, then placed in the fire on the altar for the offering; the technical verb for this action was porricere.
