however that is not the case thats happening right now.
i agree that abortion should be legal regardless of marital status. The cause for all these unwanted babies probably stem from a lack of support from a partner or thereof to begin with. Hence the life of the newborn, unfortunately ends up as collateral damage from the mother's predicament.
Better to abort an unborn then to bring them to a life of misery where they are not wanted.

I must say though however, this is a very touchy subject and has been debated since men can remember. At which stage of the baby's development cycle can you classify them as a life? or whether or not an unwanted baby can have hope of leading a proper life, etc.
