I remember your post about your aunt. I know you have been through some tough times and I am assuming you are very young. You should know that not everything is so black and white. For example lots of women have abortions who actually want a child. They might find it it has a defect that makes it 'incompatible with life'. Many of the worst abnormalities also can't be detected until 24 weeks. I am not talking about Down's syndrome here I mean terrible deformities. Things which mean he child will die within a day of being born like Edward's syndrome. That is the main argument for allowing abortions on the late side.  Most of the time this is devastating to a family and the last thing they need is a bible thumper, a politician or some ignorant random. Also it isn't that easy to avoid getting pregnant because no contraception is full proof. Even sterilization fails. IUD fails 1% of the time for example.
