"The enumeration in the Constitution, of certain rights, shall not be construed to deny or disparage others retained by the people."
And the right to privacy is real. It's not some "emanation" or "penumbra." The Fourth Amendment even clearly enumerates it.
"The right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures, shall not be violated, and no Warrants shall issue, but upon probable cause, supported by Oath or affirmation, and particularly describing the place to be searched, and the persons or things to be seized."
The right to privacy has limits, as the Fourth Amendment makes clear. And, it most certainly does not trump the supreme right, the right to live. You can't kill Grandma just because you did it in private, hiding in a closet.
The arguments over privacy have always been a silly distraction, at best, from what should be the laser-like focus of pro-lifers.
Personhood is the key to stopping this ongoing holocaust, before it has completely destroyed this free republic.
You are correct that the right to privacy - though not expressed exactly in that way in the constitution - does exist. Also, as you said, those rights are governed by higher laws. Blackmun, himself, said that the Roe decision was based upon an emanation of a penumbra within this right to privacy. So, although he admitted that there was no such expressed right to abortion, he decided it was contained within the right to privacy.
