People learn from those around them what is right and wrong. Especially the very young can be influenced by those around them.
If you are 13 and living somewhere where you’ve seen older sisters, mother, aunts, friends, people all around you, have abortions, and then you get pregnant, it will be a serious option, a doable option for you. It doesn’t matter if people outside your circle say it is a sin. That word may be, at the time, meaningless to you.
To reduce abortions in a goal to have none, you still have to understand and have compassion for that little girl in her world. She will turn on you if you come wagging your holy finger. It breaks my heart too, but it’s the truth.
