It's 1 per her Americanness, and 99 her blackness. You can explain to me all you want, but the British monarchy started the slave trade through corporations and brought over 3 million black African slaves to their colonies in the New World like America. When our founders rebelled they started outlawing slave importation starting in the 1770s and 1780s in many states, making importing slaves (controlled by Britain) into America.

So no, many Americans no enough about what a Quadroon was or the one-drop rule.
