He also doesn't think that Abortion is a Federal Issue, so he vehemently opposes the rationale of the Roe v Wade ruling.
The only rationale of Roe that matters is that the court dehumanized the child. In the written opinion Blackmun even admitted that if the child is a person, OF COURSE they are protected by the explicit imperative requirement of our Constitution.
"The appellee and certain amici argue that the fetus is a 'person' within the language and meaning of the Fourteenth Amendment. In support of this, they outline at length and in detail the well known facts of fetal development. If this suggestion of personhood is established, the appellant's case, of course, collapses, for the fetus' right to life would then be guaranteed specifically by the Amendment." -- Justice Harry A. Blackmun, Roe vs. Wade, 1973
Neither Scalia, nor any other member of this court, has ever acknowledged the simply obvious fact that the fetus is a person, even though science has removed any shadow of any doubt about when the physical existence of every single person begins.
Justice Scalia is mistaken.
