Some Indians have been known to lie about their race in order to get the benefits. Actress Mindy Kaling's brother lied about being black so that he could get into medical school. His low GPA made him ineligible so he pulled the black race card to get in.
Kamala Harris could not name her black ancestor and even went on Club Shay Shay to say that family isn't just blood, but the people you were raised around. In other words, she was trying to get around not having to explicitly say that she wasn't black AFTER her entire campaign was run on being the first black, female president. They even attacked Donald Trump for saying that he wasn't aware she was black. They also viciously attacked Janet Jackson for saying that Kamala wasn't black.
The black woman in Kamala's picture book is not her real paternal grandmother at all. A Jamaican woman who knew Grandma Beryl has already confirmed that the picture was not the real grandmother and that Grandma Beryl was a very fair-skinned, white woman. Furthermore, nobody can confirm that Kamala's great grandfather, who was a slaveowner, actually fathered an illegitimate child with a black slave, who could be Kamala's ancestor. If that was true, then Kamala's father, Donald Harris, would've said so in his biography. Donald Harris did not say that any of his ancestors were black, although he was around the black help a lot.
We do know that Kamala's ancestors were Syrian Jews, Irish, Scottish and Indian. Her father's biracial appearance may be from a mix of Irish, Syrian Jew, and Indian - NOT black.
