What are you trying to spin this in to John, these are medical issues, not pro-choice
issues, the Church has a position, would you have the Church change it’s position
over your hypothetical situation?
I think you are looking for a way to justify abortion due to unfortunate circumstances,
and I agree that your descriptions are unfortunate for anyone that has to deal with the reality of these things, but you know as well as I that abortion is used mostly for birth control, the situations you describe are not common but should have a solution via the medical community and the Church, the real problem is the steady march to the community baby killers when the mothers could have used some method to prevent the pregnancy or moral values that would have prevented the situation!
