If this view sounds ludicrous, it sounds that way because it is. Of course not. Rights are moral principles that guarantee freedom of action in a moral context. There is no such thing as the freedom to live inside another human being against their will. As it is evil for someone else to dictate the use of her body by raping her, so it is evil for someone else to dictate the use of her body by forcing her to remain pregnant.
Murder is the taking of the life of another human being through the initiation of physical force .
A right is a moral sanction for freedom of action in a social context. A fetus has no rights, as it does not need freedom to take any actions, but survives on the sustenance of its host. The only rational action it must take is nothing, i.e. wait for itself to develop using the sustenance provided by its host. Under capitalism abortion is an inalienable right. Children, unlike fetuses, do possess inalienable rights.
