John, You have a very valid point about Margaret Sanger, although I would prefer to see a citation on a statement of this fact.
But consider what happens in the Latin American countries where both birth control and abortion are not acceptable.

Their birth rate is very high in Latin America. In fact, there are many more children out on the streets abandoned than orphanages available to take them in (source: Christian radio story). Can you be sure that every baby born will be adopted or cared for if we stop abortion?
It's very easy to consider that abortion saves babies, but the lack of abortion also results in 5, 7, 10, 12, 15, and 17 year olds who are born into bad homes where the cute baby is raised by someone who was not ready to give up an adorable baby.
I personally hate abortion, because I feel that it is used as a method of birth control. However, because I feel that there are problems our society is not ready to solve if we eliminate abortions, I feel that it would be a bigger mistake to once again make abortions illegal. We may allow them to live, but as you probably know, very few women who carry a baby to birth are emotionally willing to part with a cuddly baby. But those same moms are not prepared to care for a child.
