Justice Clarence Thomas, SCOTUS, First Things - This case highlights the fact that abortion is an act rife with the potential for eugenic manipulation. From the beginning, birth control and abortion were promoted as means of effectuating eugenics. Planned Parenthood founder Margaret Sanger was particularly open about the fact that birth control could be used for eugenic purposes. These arguments about the eugenic potential for birth control apply with even greater force to abortion, which can be used to target specific children with unwanted characteristics.
