Racial classification is a spectrum determined by the amount of admixture or lack thereof one has. The one drop rule is invalid to determine concise racial determination. Multiracial suggests recognizable admixture. If any of us were walking past this woman on the street she'd be white, yes her mother was mixed, and further mixing has made this woman white with black admixture among other things. Not dealing with the race issue when the opportunity presented itself on multiple occasions now has people playing the multi-hyphenate game and doing unnecessary mental gymnastics. This is a white woman.
