Women should have a right to choose if they get pregnant because it is their body and we cannot dictate what they do with them. In most cases it is safer for a woman to get an abortion than give birth to the child. Especially in the case of women who are sick health wise already and in cases of incest and rape.
To every person who argues that it is selfish, aren't you being selfish for your own belief? If you are personally against abortion, that's fine, but it doesn't mean you should control others lives because in the end you are NOT the one who will be affected. Think of the child first of all. They would be put up for adoption and or in the foster care system. Not everyone can be a foster parent. How many people who preach that adoption should be illegal go out of their way to actually adopt a child? If it were illegal the government would be overwhelmed by hundreds of thousands of new foster children the states would have to support.
Then consider the woman and her family. If they can't afford to take care of the baby they should have the choice to abort. Do we really want to force more kids into poverty? It wouldn't be fair to them or their mothers, especially to mothers who give birth and are forced to give up their baby for adoption because they are too unfit to care for them, but still love and want their children because pro lifers think giving up your baby that you can't take care of is so easy. Or to a woman who was raped and suffered through depression until ultimately killing herself because she couldn't bear to bring her rapist's child into the world.
Abortion should remain legal because if you think about most people who try to argue against this in government are MEN when WOMEN are the ones that are affected. A fetus is only able to live because it is attached to the womb of the mother; therefore, any claim to a "right" to live must necessarily be at the expense of the woman. It is not independent. I believe that after a certain amount of time such as after the first 3-4 months when the fetus is beginning to take human form and eventually move around that abortion should be restricted and limited. Would you rather save an embryo in a petri dish or a crying 1 year old baby?
For every person who argues that abortion should be illegal, are you willing to be responsible for the health of the woman or help take care of her child?
