If you don't even believe in God, why argue for what you think He should have said? If you had read the Bible passages I referenced in my post - those that counter your claim that nothing was said abut those issues - you would have seen that there was an overriding principle behind God's laws concerning the value and sanctity of human life. That we are created in the image of God (no animal is said to have been) sets that worth. There's no "reading into" those passages what is plainly stated and directly addressed. That you don't see it is maybe because like a liberal you won't see things that ARE there?
Issues of abortion, rape, slavery, limited government and the environment are certainly not new nor are they recent concerns of modern man - they have been around since humans have existed. Though certain specifics may be different based upon societal norms of the times (i.e.; slavery vs. indebted servitude), the underlying morality of doing unto others as we would have them do to us remains the same. Without God and His established moral truths, mankind drifts towards anarchy, dictatorship and suppression of human rights. Is that how you think we should live?
I just don’t think you should claim that God is against abortion when you don’t have any Biblical proof.
