I've thought about abortion a lot - I grew up when it was illegal and saw the results of two illegal home-administered ones.
The first - I was in hospital myself when this woman was wheeled in. ER was full so they pulled the curtains round her and patched her up. The Docs and nurses went in clean, and came out covered in blood. It was clear she nearly died. When I saw her, she was so pale her freckles stood out in 3D. Hospital policy was to NEVER report such abortions to the police, but to patch the woman up, and then treat her with distain. Other patients knew this (I was only 17) and rallied round her to cheer her up. She had 5 kids, hubby was on the dole, and she just couldn't face number 6. The moral support those older women gave her was phenomenal, and it was the first time I ever saw true feminism in action.
The second was our next door neighbour. She had 8 kids, and one day sent for my Mum urgently. She was having a 'miscarriage' she told Mum, but Mum knew she'd 'done something' because she was scared of Mum getting the Doctor. Mum sent for him anyway, and before he went in, she warned him not to dob 'or else'. He said "We never do, or women would be too afraid of us, and would die". She lost a lot of blood, but survived. The Doc recommended she have her tubes tied, which she did.
I agree there is something bad about late term abortions, and I would prefer they all be done in the first trimester when we can be certain that the foetus is non-sentient. But it is essential that women have choice, or many women would die, become infertile, suffer pain and fear, or have unwanted babies born into misery.
I lost a baby at 26 weeks - the placenta had failed and I simply went into labour and it was stillborn. I was heartbroken, and the nurses told me it was a perfectly formed and beautiful little boy. For this reason i hate the thought of late term abortions, but sometimes there could be mitigating circumstances. (I ended up with two healthy sons later)
Choice is the key. No-one is going to force anyone to have one, after all.
BUt Palin would have the US return to those dangerous times for women, that I remember with horror.
