Science has a way of making things extremely objective. The issue of legalization comes more from moral interpretation ANYWAY.

If we were to be purely objective, we'd just say keep it legal. Morality stemming from science will say that a fetus is not a real human and that brain development has hardly made it an individual. so we'd say that it should be legal anyway. Now, what I would see as to why abortion should be illegal is because morality would hold assumptions. assumptions that don't ONLY put science into account. At this point, we see individual human beings in the womb, not fetuses. Even though their body and brain are majorly underdeveloped, some moral beings will see that as STILL a human, just because it can survive outside the womb if born premature. Some even say once that DNA creates something new it's an individual.

But if we start with science and create morality from that, I would say that abortion would be seen as something that should not be BANNED. Morally acceptable even in scientific terms? Who knows. It's all subjective. But legally acceptable? Yes.

If an unborn child can meet at least one of the criteria for person hood, then at that point it should be illegal to abort the child.

If the child cannot display any qualities of person hood, then it should be legal to get an abortion.

When does the child begin to display at least one of the qualities of person hood? I don't know.

Conservatives/republicans believe there should NEVER be abortions, except in perhaps cases of rape and the mothers life is in danger and things of that nature.

I disagree with that philosophy though, if someone was 4 weeks pregnant, the fetus clearly displays no qualities of person hood, it even lacks a brain. Therefore in this case abortion should be legal, but republicans/conservatives would say it's illegal.

As for what stage in pregnancy we need to draw the limit? Again, I do not know.

Some wish it upon themselves.

Yes it definatley should be! After all they say The USA is a democracy and if it is a democracy why can't we have the right to abortion. I'm not saying abortions are always the best option, but people have different opinions on what they want to do with there life so why stop them?

I think that abortion should be allowed.

Because whether you have an abortion or not is up to what morals you have and stuff.

And not all people have the same morals and beliefs and stuff like that.

Scientifically a 12 week old fetus hasn't taken human form, therefore I think it is safe to say, that it shouldn't have human rights.

There abortion should be up to what you think it is.

If an individual thinks it's murder - don't do it

If you don't think it's murdering a human, but killing a fetus and you have no moral problems with doing it, then I don't see why the government should stop you, when science supports you with the fact, that a 12 week old fetus is a fetus, not a human.

If someone is a strict constructionist who interprets the Constitution word for word, the sanction for abortion is given under the Fourteenth Amendment.

The Fourteenth Amendment of our U.S. Constitution defines a citizen “a citizen” at birth. If a woman is carrying a fetus in the womb, the U.S. Constitution does not designate the fetus as “a citizen.” It would take an amendment to the U.S. Constitution to declare a fetus a citizen. You have to be born in order to be recognized as a citizen. Therefore, a woman does have the right to choose. A fetus inside the womb is not designated as a citizen according to the U.S. Constitution so by default is not entitled to life, liberty, or prosperity. You have to be born in order to be endowed with those privileges. To conclude, neither the Federal government nor any of the States can deny a woman the right to choose.

If abortion is murder, abortion would have been terminated years ago due to the cruel and unusual punishment clause under the Eighth Amendment. Again, proof that a fetus is not recognized as a citizen of the United States of America.
