Since we know evil government would like to devalue life to the largest extent possible, why not define life as strictly and as early as possible?
I don't know if its a person or not, I just know that the sickos would love any excuse to experiment on, harvest, or kill fetuses. Why not have another layer of protections the same way crimes committed against a pregnant mother are double crimes? What society is really saying at this point is that the fetus is a person per criminal statute but the mother has the right to kill it. A chattel slave, basically...illegal under the 13th Amendment...
I just remember what Alex J. said re: abortion...."Oh you want to kill you're baby? That's ok, its not human." This is literally how the reasoning went that led us here, a classic backwards rationalization.
