Figure I'll take a swing at those guys too, Chief

The fetus is not a parasite. You do not defaecate fetus eggs and they do not infect other people. The fetus behaves like a bloody fetus. They are entirely different things. Please stop dramatizing for effect. Also, stop saying that is less than human just because it happens to be a fetus. Yes, it's similar to any other fetus, but that's because its a vertebrate in development. But it won't magically turn into any other creature while in the womb. It is a human in the earliest stage of existence. Its genetic structure is no different from yours. Don't dismiss it as anything less than human just because its in a very early stage of development. It is not a 'thing.' That's an incredibly cold and disconnected thing to say. If you don't abort it, it will grown into an individual and live life as any other human would (defects or not).
The only thing that really makes abortion halfway acceptable is not the fact that the fetus is a "parasite" (not true) or less than human (also not true). It's the fact that an embryo or fetus can't feel, think or reason in its earliest stages. Which is why I'm against late term abortions - only first term. If you're going to have one, man up and have it early. By the time you're into the third term, the kid is pretty much alive. It's just stuck in a womb.
Just for you, Lena

parasite |ˈparəˌsīt|
noun
an organism that lives in or on another organism (its host) and benefits by deriving nutrients at the host's expense.a fetus lives inside a woman and benefits by deriving nutrients at the host's expense. A fetus IS a parasite, by definition. "Parasite" is NOT divided via taxonomy. It's like carnivorous/herbivorous/omnivorous.
Assume that abortion is morally wrong, but we allow it as otherwise abortions would still occur but in a more dangerous way.
Then, why not legalise, for example, theft? If people calmly handed their money over to licenced thieves, say once a year or whatever, there would be no danger of people being killed in armed robberies and so on, or murdered for their belongings.
You claim that doesn't logically follow? With the assumption that abortions and theft are both wrong, and the facts that legalised versions of both would be safer for all involved, it seems to follow quite naturally to me.
Now, legalising theft is clearly absurd; thus we have a reductio ad absurdum, and the argument for legalising abortions solely for safety reasons falls apart.
The problem is that abortion is not morally right OR wrong. It's morality differs in a case by case basis as well as by someone's perspective.
With theft, a person is being made a victim by loss of property. With abortion, the embryo is not a person and as such, has not been afforded rights. Meanwhile the mother exercises her right to not be an incubator for nine months.
Central to the position of abortion is the concept that the fetus/embryo is not it's own person, but rather is an extension of the mother. It's a nice sentiment, but biologically it's untenable. Is a Crocodile embryo in an egg it's own creature or not? Is a newly born marsupial developmentally the equivalent of a single trimester in human terms not it's own creature?
Clearly, both of these examples demonstrate that an embryo is not an extension of the mother, and any such sentiment has no foundation in the fields of biology. The only valid interpretation is that the the embryo or fetus is it's own creature, but is wholly dependent on the mother.
Somehow I feel this entire debate would be put to rest if humans laid eggs
The difference between a reptile, a marsupial and a gestational mammal make your analogy fall apart.
