Argument from ambiguity.<p>It claims that majority-minority uses the same line of racial categorical thinking as one-drop anti miscegenation laws from (not too) long ago but applies it to cultural thinking that gave rise to the one-drop rule in the first place.<p>Skips a step in the logical process though.<p>Yes, it is true that the white race does not exist. There can be more genetic variation within a racial group than between two individuals of different racial groups. The differences in eye shape and skin color account for very little of our overall genetic makeup.<p>But US laws and customs were largely built based upon those few outwardly visible differences.<p>Whiteness exists because we made it exist. Segregation doesn't cease to exist because biology determined that there were no "races." And whiteness (as distinct from individual white people, please don't start with the whole "not all white people" stuff) is still very much prevalent here.<p>So yeah, white folks as defined by the one-drop rule are dropping to less than 50% of the population very soon. Yes, it is completely justified to say that someone who is biracial white and non-white is not considered white in this country due to its history. It's contrary to any scientifically accurate assessment of the people who live in the US, but it is 100% accurate with regard to the very real cultural, legislative, and judicial history of the US.<p>The sooner it is an old myth in folks' day to day life the better, but today is not that day.
