In the 14th, a child has to be born to be a citizen. Read later that it says ‘nor shall any state deprive any PERSON (not citizen) of life, liberty or property...”
It does not say that you must be born to be a person but you must be born to be a citizen.
Is it legal to murder someone (a person) in this country illegally (a non citizen)?
Why is legal to kill the unborn (person) just because they have not been granted citizenship (born) yet?
Amendent 14, Section 1: All persons born or naturalized in the United States, and subject to the jurisdiction thereof, are citizens of the United States and of the State wherein they reside. No State shall make or enforce any law which shall abridge the privileges or immunities of citizens of the United States; nor shall any State 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.
I emphasize with the connection that you are trying to establish between Sec. 1 of 14A, Congress and the legal definiton of personhood. But I think that John Bingham, the main author of Section 1, simply did not foresee eventual problems with the wording of Sec. 1 and abortion.
After all, as I mentioned in another post, pioneering parents deliberately had many children because they could not expect all children to survive to adulthood. And those that did survive certainly had their share of farm chores. So Bingham was probably not concerned with abortion when he drafted Section 1.
