Other than rape, a woman chooses to engage in activity to become pregnant. Adult women are not children, and are capable of making rational decisions. Rape would be a mitigating factor, presumedly.
Look, the reality is that chance that women will be put in jail for having an abortion is nil. However, it is a logical contradiction that somehow if a woman who is 39 weeks pregnant hires a doctor to perform a partial birth abortion she should be off the hook but if she hires someone to murder her day old newborn she should serve 20 years in prison. It means that despite the rhetoric, even most pro-lifers do not see the unborn as having the same status as those who are born.
You don’t think children become pregnant? There are women who have been victims of incest and they were willing only insomuch as they didn’t have much of a choice but it would not legally be considered rape. There are just too many scenarios. As for the PBA, well, that should already be a criminal action IMHO.
