“A small group of lobbyists who supported, along with eugenics, traditional principles of family and government, promoted Virginia’s Racial Integrity Act of 1924 as part of a wave of legislation that sought to control marginalized populations”
Lisa Lindquist Dorr writes about the eugenics movement in the 1920s. The government has long since been controlling the family life of everyone, and now that white woman have been taking a stand (although they are still very much regulated but minorities are much more controlled) the government went as far as eugenics to prevent the non white women from reproducing and furthering the racial differences. While white woman at this time are being encouraged to have babies the minority groups are literally having their ability to do that stolen away from them.
