I am one of those pro-choicers - even more so now than I used to be - but totally understand why people who support third trimester abortions oppose more restrictions. IOW I am totally objective about all sides of the issue, basing my opinions on biology, psychology, and sociology as well as my faith. I hope none of the CF posters who disagree with my specific views on abortion will attack me for disregarding the Bible - I really don't - by being a realist and patriotic American woman.
Anyway, what I meant in my post was restrictions on safe abortions would cause more dangerous (for the mother) abortions. If a pregnant girl or woman is desperate enough, she will not will do whatever it takes to have an abortion within her ability. If she can't travel to Canada, the only country in the world that has no restrictions (according to a pro-choice friend who lives there), she will look for a person who has never had formal training to dissect her abdominal area and remove the fetus, amniotic sac, umbilical cord, and placenta. What are the chances that person made sure everything is sterile? I think close to zero.
Now, this is not to say I support abortions for any reason. I hate eugenics. Wanting a baby until she finds out it is not the right sex is totally unacceptable. You either want a baby or you don't. If a defect that has no life-threatening consequences or is highly treatable is diagnosed, a loving mother would accept that as part of being his/her mom. But this requires a change in attitudes; morality cannot be governed by a law. So when it comes to the severely defective babies everyone knows will die before or shortly after birth, in all cases it should be the mother's decision because her morals in this situation are totally subjective.
