Many Muslims believe it is OK to crash airliners into buildings. Stupid people exist in every faith.
The story of Genesis is symbolic, but taking for face value - Adam wasn't born, he was created...by God. Not by a woman's choice to carry a pregnancy, but by God's hands. At the point of conception God has already taken dust from the earth and formed a life. If you believe God created (and creates) life, how could you possibly believe that it is up to a woman's vagina to give that life a soul? That goes against Genesis. It implies God is imperfect and his creation needs a woman's consent or approval to be validated.
Besides, there is no clear indication of when God breathed life into Adam's soul. You could just as easily interpret that as saying the breath of life is conception.
Source? It clearly teaches that life comes with God. His hands, his decision, his plan. A woman's choice, validation, or vaginal canal have nothing to do with it.
Which you probably didn't even read or understand. Laughably, it quotes the Old Testament (Jewish law) as Christian teaching, which is absurd.
Going by Exodus 21, a man owns a woman and we should all practice an eye for an eye. Of course, that is direct violation of what Jesus said in Matthew (5:38-42) - "Ye have heard that it hath been said, An eye for an eye, and a tooth for a tooth: But I say unto you...turn the other cheek".
You might have more like using that argument as to why Jews should have abortions. Even then, it would be a balls argument since Exodus 21 says nothing about where life begins. It simply says that a premature pregnancy caused by beating should be punishable by what the husband demands.
You have a very dangerous, and equally incorrect, interpretation of Christianity. Can't even get the fundamentals of the faith right, let alone construct the ability to argue with thousands of years of accomplished scholars and saints who disagree with you. Try harder.
