It has to be the right of each individual woman to choose what happens to her body. It is also true that, in some cases, not Be I Ing born is perhaps the better option.
I know of a young woman who is currently expecting a baby as a result of rape. She chose not to have an abortion. This is the second baby she has had after being raped, possibly because she is a crack addict and gets herself into dangerous situations when she is using, and possibly because she is small and vulnerable. The first child was taken away for adoption before her first birthday, because the young woman couldn't parent her properly. Her own childhood had been horrific and she had no idea how to be a mother. During both pregnancies, she tried to give up drugs and would be clean for long periods of time, but then the addiction would be too strong and she would go back on crack. She has been repeatedly warned that it may damage the baby but the need for drugs overwhelms her. Afterwards she loathes herself and wants to commit suicide. When this baby is born, it will probably be addicted too. It is likely that it will have permenant brain damage. When it is born, it will be taken straight into care.
I can't help thinking that maybe abortion might have been the better choice. That baby is suffering in the womb. Every time that its mum goes through withdrawal, baby does too. God knows what damage is done when mum goes back on drugs.
Maybe it will be undamaged. Maybe it will get wonderful foster parents who cope with a drug dependent baby, and loving, patient adoptive parents. But maybe none of those things will happen and it will be condemned to a miserable life before it is even born.
That's just one example of a case where non-existence might be better than existence, and at least her mother had a choice. If that choice is taken away from American women - and if it happens in Texas, it will happen in other states - how many damaged, unwanted children will have to be born? And the US system is harsh. There is very little provision for people who can't make it on their own.
My DD in the US says that abortion is a much more controversial political issue over there. She knows several people, including women, who wouldn't vote for Hilary Clinton because of her support for Roe vs Wade.
