I learned that abortion was wrong before I learned what abortion was. I later learned that abortion was murdering an unborn child. I learned both of these things from Christian rock songs.
A typical example was “Who Will” by DeGarmo & Key, from their 1989 album “The Pledge”, which I found for £1 in a Christian bookshop bargain bin in about 1992. I was seven at the time. I never actually liked “Who Will” very much, but I heard it a fair bit because my dad played the whole album in the car. He never talked to me about the lyrics or what the meant, but I took it that everything therein had his approval since it was Christian and he kept playing it.
