I know this is a race post but this is a serious question that SO and I don't agree on. If it gets out of hand I will delete it myself.

White passing - someone who is non white but has European features and could easily be mistaken for white.

POC- person of color - - non white person

To clarify question 2, I'm asking if a white passing poc can continue the concept of white supremacy even though they aren't white.

Ex. A woman who is black and white but has light hair, colored eyes and is often mistaken for being full white. Could she benefit from white privilege since people think she's white ? Would she be more effective in continuing the idea that white people are the superior race vs a biracial woman who resembles more of the black race attempting to perpetuate white supremacy?
