I realize that many non-Catholics who are pro-abortion make the argument that a "fetus" is not a person, or does not have a concept of personhood.
If that's the case, how do such people define "personhood?" Do they define it based upon age? For example, is a 2 year old a rational human being, therefore a "person?" Why do toddlers have unalienable human rights but an unborn child does not (an unborn child, afterall, is technically a human being, therefore rational, and essentially a "person?")? Are those who are disabled/handicapped/special needs considered "persons?"
Is their version of personhood determined by how developed a child is in the womb? For example, is a baby at 4 weeks old "less" than a person as he/she would be at 18 weeks after fertilization? How would we know exactly what stage that a "fetus" becomes a "person?"
Is it based upon being "alive?" I know that pro-abortion people make the argument that a "fetus" is not alive, or not "developed" enough to be a "person" yet. A "fetus" technically exhibits all the scientific characteristics of "life" (or at least, what we currently know about it), so I would think the idea that personhood=being "alive" is a false one.
When I was still in my mother's womb, she said that she never considered me a "fetus." I was her "baby," her "child." I would certainly not see any potential future offspring of mine as "fetuses." To her, I always had personhood from the moment of conception.
I know I'm going all over the place with my questions but it truly boggles my mind as to how illogical all this seems..upon birth a child is considered a person, but that same human being that came into the world upon conception is not a person or "less" of a person? I am not a philosopher nor too educated in philosophy in general, but I am a scientist.
I am just, overall, wondering where pro-abortion people get their concept(s) of what defines "personhood."
