A fetus is a fetus is a fetus. A child, is a child, is a child and never the twain shall meet. At the moment a child comes into existence, there is no longer a fetus, and that moment is with the first breath of the child, outside the womb. And I still do not understand what the heck you mean by "not providing a uterus"?
A fetus is essentially a child, regardless of this distinction which is mostly subjective, I dont see why being a child necessarily changes one's rights from when one is a fetus. Killing a fetus is fine in the same way killing a child would be fine if the child had no mind.
A child is a human being, of a particular age, a baby is a much younger human and a toddler is kinda in between. A fetus, since it does not breath, eat, or defecate is NOT a human being or for that matter, not any other animal. It is a parasitic growth in a human being, with the potential, given enough time of POSSIBLY becoming human. The law makes abortion legal, no other understanding needed. The law seldom makes sense, although in this case it does, partially. The law just is.
A fetus is not human, it is a parasitic growth in a human. It may, or may not have (given enough time) the potential of becoming human, but until birth, it is NOT human.
It can only do those things with the assistance of its mother. Again, I could use the machine example -- if someone was latched to a machine that did all those things for them, do they cease to be a human being? This is the problem with making definitions out of thin air... they're wrong. By biological definition, the zygote is human. Any site will tell you that, even if it's pro-choice. This is from a pro-choice article entitled Why Abortion is Moral: http://www.elroy.net/ehr/abortionanswers.html Let me stop you right there. If you want to base your ideology off of what your government says, and there's no need for other understandings of any issue that the government has already ruled on, what are you doing at a political forum site? What are you doing talking about politics at all? You should be happy with what the government rules on, if the law is the only understanding needed. Of course, if you take a trip to Brazil, I suppose your abortion position will be pro-life at the time, then, when you get back here, you'll be pro-choice again.
The point is that the fetus can not maintain its own life or homeostasis with its own organs. A human being can. They are routinely disconnected. Yea and your problem is understanding plain language. Biological classification does not make a being.
