“Roe isn’t really about the woman’s choice, is it?” Ginsburg said. “It’s about the doctor’s freedom to practice…it wasn’t woman-centered, it was physician-centered.”
“My criticism of Roe is that it seemed to have stopped the momentum on the side of change,” Ginsburg said. She would’ve preferred that abortion rights be secured more gradually, in a process that included state legislatures and the courts, she added. Ginsburg also was troubled that the focus on Roe was on a right to privacy, rather than women’s rights."
