Shoot my response to using the word parasite didn't post from my phone!
Anyway, larry, you comparing a living woman to a bunch of machines is a false comparison, even though it takes humans to support the machines. A baby is taking things from another living thing, it's mother. A person on life support is taking things from a machine, not the same thing.
There are tons of parasitic and symbiotic life forms in the world. Your argument that if it was a parasite the body would reject it is also wrong, as lice, for example, are parasitic. The body doesn't reject them. If it did we wouldn't be calling for the return of the Nit Nurse. 
Also, I did say that I didn't like the word but I really can't think of a better one.
I will never agree that an unborn baby is just as important, or more important as a lot of pro-lifers imply, as a mother. There are always things that are more important that other things.
I also would like to applaud all of us on this thread for having a pretty much reasonable conversation rather than a bun fight on this issue. I am very impressed we have not name called (much
) or cursed at each other.
