Note that corporations are "persons", but that an unborn fetus is not a legal person.  A "person" is an entity that has certain rights that are recognized by all.

It seems that only anti-abortionists think of zygotes, embryos, or fetuses as persons -- although the number broadens when a fetus becomes "viable".  And although I think that a viable fetus that doesn't threaten its mother should be allowed to be born, I still don't really care that much because it doesn't think, it doesn't have emotions, it isn't conscious, makes no intentional attempts to communicate, and I can't shake hands with it.

It isn't a person, as I understand the word.

But I might be wrong once it becomes viable, so I'm interested in seeing that pregnancy proceed normally.  Nevertheless, I'll give the person, with whom I can shake hands, the benefit of the doubt in all other situations.
