The Troubling Ideals at the Heart of Abortion Rights

Many Americans think of Roe v. Wade as the defining Supreme Court decision on the issue of abortion. But a 1992 high-court decision actually governs abortion law. That ruling rested on fateful assumptions about the relationship between abortion and women’s equality.
