One thing that has always perplexed me about the "passing" phenomenon is that people who would outwardly appear white, live in majority white areas, and marry white spouses would still be considered Black by society if they had any identifiable quantity of Black bood. At what point do people with African ancestry stop being Black? Is it even possible? Should a self-identified "white" who is 1/32 Black and 31/32 white honestly be considered a Black who is passing, instead of a white person with a Black ancestor? When does "passing" end and actual "being" begin?
