Maybe the first question should be about the unborn child - at what point does a fetus 'inherit' the right to life? Should the act of birth confer that right? What's so different between the baby 5 minutes before it's birth and 5 minutes after? What about the point at which doctors and scientific evidence says he or she is viable? Should we consider his or her rights in the decision to end that life?
As far as the father's rights in the decision, maybe he shoulda thought about that before he dropped his drawers. If he didn't care about it then, well it's a bit late to assert your rights later. Did you and your partner discuss this at all? Were you personally trying to father a child? Was she also trying to get pregnant? But the bottom line is, the female is the one who got pregnant and the female is the one who has to carry the baby to term and the female who has to go through the birthing process. So IMHO, her rights and decisions trump yours.
Nobody wants to go back to the days of coat hangers, right? We simply cannot leave a young woman, in many cases underage, with that as her only option other than to carry the baby to term. It's easy for some to say tough shit girl, maybe you shoulda keep your pants on and legs together, but maybe that wasn't an option in rape or incest cases. In any event, we've gotta offer more options. Such as: free contraception for both boys and girls in high schools and even junior high, or at as many clinics as possible around the country. And also the so-called morning after pills too. Beyond that we've gotta improve our adoption services for babies that are given up by their young mothers, and remove or at least reduce the stigma against unwed mothers. It isn't as bad as it used to be when I was a kid but there's probably still a ways to go.
IMHO, Roe v Wade is a flawed law with no precedence in the Constitution or existing law prior to 1973. One could say we needed it to get past the coathanger days, but I think this issue probably belongs to each state to work out their own laws, with the federal courts ensuring that the rights of all are fairly and impartially considered. And IMHO that should include the unborn, at least after reaching viability. That's just me though.
