In my opinion, abortion must be allowed in cases when a woman gets pregnant because of rape. And that's the only circumstance where I advocate it. A rape-victim can't be forced to carry out a "baby" that starts to exist solely because of a horrid crime. Of course, the way it was created is not the fetus' fault, but again, it is a woman's body and if she doesn't want to carry out that baby because it pretty much becomes a monument of the rape crime, a torment, then so be it.
If a couple (not only the woman) is too stupid to use contraceptives, then it's their own fault and they have to deal with it. In that case abortion should be illegal. If you can't take the responsibility and can't be careful enough (which isn't that hard, since there is even a thing called "morning-after pill"), then don't have ***, simple.
Anyone who says "yes" or "her body her choice" should have gotten aborted. It is moraly wrong, weak, and disgusting, if you don't want a child then don't have ***, or wear protection, if not then it's your responsibility.
Should abortion be legal so should murder.
You try to make it very easy for yourself. What about rape?
