Assuming consentual sex, I feel there is a moral obligation to discuss things like pregnancy, birth control, abortion, children and STDs BEFORE having sex. That is usually not the case, but the moral obligation does not go away, and the discussion should still happen. However, I believe that there is no legal reason to force the issue.
Personally, I disagree with abortions, save in the most extreme circumstances. I feel it is murder to take a life created by consent, except for the mother's own life. Still, I believe abortions should be legal, because I do not believe the justice system is capable of picking out the situations that clearly call for them before the child is a toddler.
Making abortions illegal does nothing to rectify the reasons women seek them in the first place. We should correct all the problems that create the undesirable result, and then we will, perhaps, see positive change.
