I haven't read the entire thread, but quite a lot of it...
I don't understand how anyone can say they are anti or for abortion unless they personally are faced with their own dilemma.
I was always in the anti abortion except if raped category, til about early 20's. Then my room mate in halls of residence went on an anti abortion protest, came back with a massive poster saying "abortion kills children" on it and stuck it on our room dor on the outside. I was mortified that someone might think they were my views, and it certainly made me question them, as I thought I agreed with her. I was anti abortion for me personally, but it's a personal choice.
I then had my son as a single mum at 29 (unplanned) but I was ready for a child, with or without the boyfriend and knew I could provide a good life for him. Whilst bringing him up alone for 3.5 years, I fell pregnant again, with different person. I had an abortion. No one persuaded me into it, but I rationalised by thinking...I'm still single, I will have less money, more tied to raising children rather than working, 2 different fathers yet still not with anyone, so who will want me, blabla. I get sad on occasion and it was a bloody horrible thing to have to go through, but I don't regret it.
I met my husband and within a short space of time, fell pregnant (planned). Sadly, we lost the baby at 16 weeks' pregnant. They don't call it an miscarriage, they call it an abortion. This was due to me having no choice but to take a pill to induce giving birth as it was so late on. I had no choice because due to haemorraghing (can never spell that word) I got an infection. If I took antibiotics, the baby would die. If I didn't, we both would have died. So no tough choices, but a heartbreaker nonetheless. We were even made to go to the funeral for him and my husband carried the coffin...a torturous time for us, even now when we talk about it.
3 months later, I fell pregnant again, we got married, and now have a lovely 5 month old ds. And pregnant again! (Also planned). So life is good now, even tho we've had some shit along the way.
I guess what I'm trying to say is that everyone's life is different, and needs to be considered carefully, and personally. No one will live it but you, so those with strong opinions, please be more sensitive!
