I want to know the answer to the following question:
What fact was ignored by enacting one-drop rule laws?
All the background I'm provided with is that "Racial discrimination continued to be enacted in new laws in the 20th century, for instance the one-drop rule was enacted in Virginia's 1924 Racial Integrity Law and in other southern states, in part influenced by the popularity of eugenics and ideas of racial purity.". Is that enough to answer the question?
Answer: no
