The moment on the human life continuum that divides viable from not viable is a biological fact not a scientific creation.
Yes, and obviously not constrained by an arbitrary date! What part of this do you not get. In many cases a 23 week gestated fetus can be just as, or even more developed than a 24 week fetus!
You give arbitrary protection to one, but not the other.
Your argument is therefor baseless. 🤦♂️
