Not many people would see a pregnancy as a good thing to come of rape.
Thats because they aren't omnicient --- they can't see the end results - only see the immediate outcome. God would never allow the pregnancy if it weren't part of a bigger picture. Christians understand that bad things happen for a reason and that we (people) are WAY to insignificant to be able to understand all that is in work in God's hands.
To many liberals get the idea from their religion, secularism, that their wants and desires are the most important thing --- that THEY can determine what is good and/or bad.
If that child born of rape was intended to get the mother off drugs so she could make a stand against rape - and change the world in a good way... think about it....
Or the most obvious (albeit fantastic) the child itself could have a child that would become President.
A child born of rape isn't a bad thing because secularists say so any more than a child being born of rape is a good thing (if you could find a Christian to say so). A worthy intellectual debate - perhaps... but as a Christian, I also realize that God wouldn;t allow that important child to be aborted. Lots of children are born as a result of rape - as most rapes aren't even reported. God - not secularists - determines that as well.
