Not only do I think she has a white mom, I am all but certain her black daddy left her and her white mom. It is often the case.
Much like our former president who benefited greatly from his white relatives, yet called his grandmother a racist and hero worshiped his womanizing drunken father who left him destitute mere moments after his birth. Thus requiring his maternal grandparents take care of him while his whore mother continued to pursue other black communists. .
Because they grow up in the white home fine until they get to about middle school where they are exposed to blacks who call them uncle toms and house n——rs and demand they say and do things to prove their blackness. Then they start to get hostile toward their white family, and it’s all downhill from there. Tragic, really.
