In a gloriously brutal concurring opinion published Tuesday, Justice Clarence Thomas took on Planned Parenthood, the meaning of abortion, and birth control. While writing a concurring opinion in Box v. Planned Parenthood, Thomas likened abortion to eugenics and scolded Justice Ruth Bader Ginsburg for nonsensical opinions in the same case.

Thomas wrote his opinion in response to the court’s opinion about Box, which addressed two provisions in an Indiana law. The first provision prohibits abortion providers from treating the bodies of aborted children as “infectious waste” and incinerating them alongside used needles and the like. The second provision “made it illegal for an abortion provider to perform an abortion in Indiana when the provider knows that the mother is seeking the abortion solely because of the child’s race, sex, diagnosis of Down syndrome, disability, or related characteristics.”
