"In responding to my analysis of this case, MR. JUSTICE WHITE has described the constitutional right recognized in Roe v. Wade as "the right to choose to undergo an abortion without coercive interference by the government" or a right "only to be free from unreasonable official interference with private choice." Ante at 448 U. S. 327, 448 U. S. 328. No such language is found in the Roe opinion itself. Rather, that case squarely held that state interference is unreasonable if it attaches a greater importance to the interest in potential life than to the interest in protecting the mother's health. One could with equal justification describe the right protected by the First Amendment as the right to make speeches without coercive interference by the government and then sustain a government subsidy for all medically needy persons except those who publicly advocate a change of administration."
