The women you refer to are often very young, and under duress from boyfriends, parents, and society in general to "be rid" of this problem.  I had my child at 17...and she and I did just fine.  BUT had abortion been available then...I can not honestly say I wouldn't have used it...out of fear, ignorance and desperation!  Very few "Women" are making these decisions.  This is the problem in a nut shell...primarily little girls are pregnant and the "CHOICE" THEY ARE GIVEN...IS NO "CHOICE" AT ALL.
This is why abortion need to be illegal...because most young girls are coerced into ""CHOOSING"  their baby's death! 
Should I have been pregnant at all?  Certainly not!  But there I was...and here they are.  What are we going to do to help them, after we rid society of this horror that is called abortion?
