By definition, a fetus does not possess rights because the things in nature that give rise to rights are human individuation and the power of choice, which in turn gives rise to moral agency.
A fetus, however, is the diametric opposite of individuated: it lives parasitically (in a literal sense) off of an individuated host. For this reason, the right belongs exclusively to the host — i.e. the woman — from whom that fetus derives life entirely. When the fetus is born, it becomes individuated, and that is when rights begin.
On this issue, as on many others, I am in complete disagreement with the so-called rightwing and am more aligned with the so-called left. And yet here’s one thing I’d like for someone to tell me:
How does it then follow that because a woman does possess the inalienable right to choose abortion or not, I or anyone else should therefore be forced to fund the abortions of others, as Barack Obama and the leftwing all believe?
Answer: it does not follow.
My rights, your rights, everyone’s rights stop where another’s begin.
