No State shall...deprive any person of life, liberty, or property, without due process of law; nor deny to any person within its jurisdiction the equal protection of the laws.
Even Blackmun, in the written Roe vs. Wade majority opinion, openly admitted that "if the fetus is a person," they are "of course" protected by the Fourteenth Amendment.
So, he and his colleagues dehumanized the child.
But we have pro-choice for states Republicans running around admitting that the fetus is a person, as it clearly is by any modern scientific measure, and yet are still saying that the states can allow them to be killed if they want.
I say the latter position is worse than Blackmun's.
