As for why we think a fetus is a human being, we resort to science to explain why...
Advocates of privacy rights correctly understand that a fetus is not legally a person, entitled to Constitutional protections, and the Constitution explains why:
After analyzing the usage of "person" in the Constitution, the Court concluded that that word "has application only postnatally." Id., at 157. Commenting on the contingent property interests of the unborn that are generally represented by guardians ad litem, the Court noted: "Perfection of the interests involved, again, has generallybeen contingent upon live birth. In short, the unborn have never been recognized in the law as persons in the whole sense." Id., at 162. Accordingly, an abortion is not "the termination of life entitled to Fourteenth Amendment protection." Id., at 159. From this holding, there was no dissent, see id., at 173; indeed, no member of the Court has ever questioned this fundamental proposition. Thus, as a matter of federal constitutional law, a developing organism that is not yet a "person" does not have what is sometimes described as a "right to life."
Planned Parenthood of Southeastern Pa. v. Casey, 505 U.S. 833 (1992)
The courts have wisely and appropriately left the matter of when life begins to individuals to decide, based on science, religious dogma, and one’s own good conscience, free from interference by the state.
However ‘scientific’ you and others on the right might perceive conservatives to be, science is not the sole factor with regard to resolution of the issue, where any resolution must comport with the Constitution and its case law.
He said, as if there were anything scientific about the political motives and agenda of the political left. . . .
Life indisputably begins at conception. The Court's baby talk notwithstanding, that's a scientific fact of material reality.
The question as to when a living human being becomes a person under the aegis of constitutional law is the issue that is purely philosophical or theological in nature, or the stuff of political theory and governance.
What the Court actually did is contrive out of whole cloth a doctrine of privacy for postnatal human beings against the interests of prenatal human beings in regard to a matter that had always resided within the purview of the several states, not that of the federal government, in spite of the Fourteenth Amendment.
Why?
While it's indisputable that the Constitution ascribes personhood to postnatal human beings only, any doctrine of privacy asserted on the behalf of a person at the expense of the life of another human being entails the act of divorcing constitutional law from its foundational, ontological justification: natural and divine law.
Do that, that is to say, subvert the first principles of legitimate government, and the Constitution can be made to assert virtually anything one pleases.
The sociopolitical construct of our Republic was not predicated on the secular-progressive's ontological justification, such as it is, but on the Anglo-American tradition of classical liberalism: the construct of universal inalienable rights, wherein the sanctity of human life and the biological family of nature are the first principles of private property, backed by an armed citizenry.
Prufrock's Lair: Abortion on Demand, Homosexual "Marriage": what will they think of next?
Leftists perceive the right of privacy in regard to so-called reproductive rights to be the stuff of freedom. This construct is merely a euphemism denoting the use of abortion on demand as a method of birth control. It's not freedom at all, but the license and perversion of mindless animals that undermine the principle of the sanctity of human life. Such inevitably demand that the government transfer the wealth of others to them in order to ameliorate the consequences of their immorality.
The federal government did not give up any power at all by undermining the authority of the several states and the people thereof to assert the sanctity of human life against the whim of murderous renegades, particularly that of pseudo females. Under the terms of the original social contract, the body politic does have the right to legitimately insist that all of its members safeguard the lives and provide for the wellbeing of their progeny, fulfill their responsibilities toward them, from their conception to the moment they reach their majority, as their progeny ultimately belong to God, not to themselves or the state.
Until
Roe v. Wade, the constitutional imperative that the government protect and promote
the political rights of all persons never precluded the right of the several states and the people thereof to protect
the lives of prenatal human beings and prevent the federal government from subverting the underlying justification of the social contract and thereby elevate itself above the authority of the Creator, Who is the only legitimate Source and Guarantor of human life and liberty. In
Roe v. Wade, the federal government grabbed power and declared itself to be the giver or arbiter of human rights. Hocus pocus. Now you see it, or maybe you still don't.
Don't you know that evil is never satisfied with keeping its license and perversion to itself? There's nothing private about it. The demands of illegitimate rights will always necessarily be asserted by the state against the natural flow of things at the expense of human life and liberty. In history, what statist regime has
not foisted the burdens of the supposedly private affairs of those who violate natural and divine law on the prerogatives and the property of others?
