I own that system and the State can just kiss my ass. It is not the child's body until the child separates from the woman and survives on its own. Technically, a parasite, deriving all its substance and sustenance from its host at a very high metabolic cost. Many women bear this burden happily, which is a good thing. Those who don't, enjoy the right to rid themselves of the burden.
Life is a gift from mother to child.
Forcing a woman to bear an unwanted child is as much a perversion of that gift as rape is of making love. In terms of when life begins, I believe that life has no beginning and no end, only different stages. We are all on the endless circle of life. The physical world is always in a state of change. Things come into being, manifest, and then pass away.
