Just going by some very public examples of biracial people, it seems like when a white and a black marry, the kids grow up and hate whitey (Colin K., Megan Markle, Deblasio’s weird daughter, Obama).
Especially considering the real integrators according to these stats are Hispanics and Asian. Either way they always embrace the “cool” ethnic side and disregard their whiteness.
That's also why demographics are such in this country that it's going to be almost impossible to win a national election for a conservative or even a Republican.
