Yes, many pro-lifers such as myself are pro-life after the child is born as well.
That said, I subscribe to the Consistent Life Ethic which means that I am against abortion, the death penalty, human cloning, embryonic stem cell research, euthanasia, and any other attack on the dignity of human life.
Euthanasia is not an attack on human life. In 99% of cases non-voluntary euthanasia is actually illegal, so when people talk about euthanasia they are usually talking about euthanasia with the patient's consent (through writing a will or stating it in some way). It's the patient's decision to die. I'd personally prefer to have that option for myself if I ever want to take it.
It's also a bit idealistic to assume that charities alone (and why church charities? Not everyone is a Christian) are enough to get people a good quality of life. Maybe your local priest has won the lottery, if so congrats, but this is hardly the case where I live.
Also, it's not just about material things but psychological ones too. Rape can have very traumatizing and long-lasting consequences (including PTSD) on people, it's just not the best state to be in when raising a kid, much less one that resulted from that rape. Additionally, you can't possibly know the life circumstances of everyone who gets an abortion. If a young girl is being raped on a regular basis by her father and gets pregnant, do you think that's a good environment for a child? If so, there's something very, very wrong with you.
Not just that, but abortion is often medically recommended. Why? Because sometimes it's a matter of choosing between the life of the mother and the life of an unborn fetus. Sometimes a fetus may not even survive for very long after birth and would just agonize for hours in pain after being born.
You have the right to choose to not abort if you ever get pregnant, but it's unfair to try to impose your views on people, especially people who are probably in much worse circumstances than you ever will be.
EDIT:
Lol - "welfare mom". I'm sure that's the height of aspiration for a teenage rape victim.
I can't call that "help" with a straight face. Sorry.
Exactly, this post sums it up. It's not really "help" to make things worse for someone.
P.S.: I'm not American but this seems to have turned into a general conversation on anti-choice vs. pro-choice.
