kamala is not black! do you people have eyes?
Yes she is
In America, anyone with African ancestry is considered black. The legacy of the one drop rule is strong. That is why mixed race children are called either mixed or black, but never white. Kamala's father is from Jamaica, whose ancestry is from Africa.
Does the black community in the United States claim her as one of their own? For the most part. She isn't any different from Obama (whose father was from Kenya) but for some reason Obama was "one of them".
The black community consider Harris one of them, but not that much
*Anyone with significant or noticeable African ancestry, that is. The interesting thing about Kamala is that her racial background (half Black/half Indian) is common in Jamaica and the rest of the Anglophone Caribbean.
Jamaica (and other Anglophone Caribbean countries like Trinidad, Guyana, etc) has a sizable population of people of Indian descent (whether full or partial). They are the descendants of Indian indentured servants who were brought to the Caribbean by the British during the 1800s and early 1900s. They were brought to the Caribbean to do the work in the plantation fields after slavery ended in the 1830s in the British-controlled Caribbean.
Indo-Jamaicans (whether full or partial) are culturally different from Indians directly from current day India though. Most Indo-Jamaicans are culturally and socially the same as Afro-Jamaicans. Also, Indo-Jamaicans will almost always identify as "Jamaican" first and foremost and not as "Indian". There is the legendary dancehall artist Super Cat and he is half Afro-Jamaican and Indo-Jamaican. Miss World 2019 Toni-Ann Singh is also half Afro-Jamaican and Indo-Jamaican.
The most common term for a person who is half Indian/half Black in the Caribbean is "Dougla". However, in Jamaica, the term "coolie" (which can also refer to someone who is fully of Indian descent) is more common. Some consider the term "coolie" to be offensive but in Jamaica it isn't considered to be offensive (for the most part).
