This is probably going to go down in flames, but I am going to say it anyway.
The woman should have a right to choose because she is the one carrying the baby. Majority of the time she is also an adult too - an adult who has the right to vote, make decisions and who possibly is already loved by many others on this earth (friends, brothers, sisters, parents, existing children)
The baby is a life, yes, but it has not 'lived' life in the outside world.
It does not know what it is to see, to understand love, to experience life as we do every single day.
The fact that it will not go beyond the womb is sad, very very sad, however, it cannot make decisions for itself, therefore the mother who is carrying that baby has to make those decisions.
The baby's life cannot come above the mothers, because in those terms, the life is not equal.
Until the baby is born, there is no guarantee that any baby will make it to birth. That is a sad and true fact. The mother is already a living and breathing person.
It is not for someone who does not know or understand the mother to make that decision.
I would like to add that I am currently pregnant with a baby which was very much wanted and planned for. I feel sad thinking about abortion, for the baby yes, but also for the mother who likely would have gone through an enormous turmoil in making that decision.
But it still must be her choice.
