What is more important? Choice or life? Please choose your choice (response) if you are alive. If you are not alive, you cannot even choose to answer my question. You cannot have a choice if you are not alive.
People who are for abortion are pro-choice. People against it are pro-life. You cannot have choice without life. If your mother aborted you, you would not be allowed to be pro-choice because you would not be alive.
The first question you must ask yourself before you can pursue this question is what is a person? What are the conditions to classify someone as a "person"?
I tend to stick to the philosophical definition of a person as a "moral autonomous agent". In other words, a person must be able to think for themselves and must be able to decide between right and wrong before we can consider them a person.
Now this is a strict definition, as we wouldn't generally classify say a two year old child as a person(as they do not know the difference between right and wrong yet, ie. are not fully autonomous), so I would like to relax it for this discussion.
A person for this discussion will be an autonomous agent; a being that can think for itself.
The brain of a foetus starts to develop at about week 4 in the pregnancy. At around week 9, the nervous system is developed to a stage where it is quite functional. With our relaxed definition of person, we can say a foetus becomes a "person" between Week 4 - 10 when the brain is developed to an extent to where the baby can interact with its surroundings; its reality.
Hence, before week 4, the foetus really isn't a person and I don't see a problem with abortion. It is equivalent to the death of sperm in that the foetus is not a person. Between weeks 4-10 whether an abortion is okay or not would need to be researched to determine whether the foetus could be classified as a person. After week 10, I would say the foetus is a person and shouldn't be aborted.
However, I will grant exceptions to this, and this leads onto your argument that the aborted baby wouldn't get a chance to voice its say. Lets say the baby develops a severe genetic defect that would hinder it for the rest of its life. Would it be wise to bring that child into the world knowing that it will go through major pain throughout its life? Would it be wise to bring that child into the world knowing that their genetics could bring about the same defects in other children? Should the parent be required to undergo major stress in their life for a genetic mutation in their child?
At that stage, it should be up to the parent whether or not to abort their child, and that choice should be available for them up until they are ready to give birth.
