A fetus does not have a right to be in the womb of any woman, but is only in there by her permission . This permission may be revoked by the woman at any time.
Murder is the taking of the life of another human being through the initiation of physical force .
Rights only apply to human beings , and not to human tissue . 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 action it must take is nothing, i.e., wait for itself to develop using the sustenance provided by its host. Given the above, under capitalism abortion is an inalienable right. Children, unlike fetuses, do have rights.
