Referring to an embryo as a child or human being is more than a little specious. This rhetorical device is commonly used by self righteous deists in an attempt to inflame the debate surrounding abortion affording them license to hurl accusations of "murderer" and "baby killer" at women who are seeking an abortion. To anyone who has even a basic knowledge of biology it is quite evident that an embryo is a potential human being, in fact, from a strictly zoological term of reference an embryo is a parasite ie. An organism that grows, feeds, and is sheltered on or in a different organism while contributing nothing to the survival of its host.
