About Cecil the Lion vs. abortion

To my friends criticizing the attention given to a lion when babies are being killed: I agree we need a change of heart. I agree that human life is infinitely precious. But I suggest that rather than criticizing the outrage over the lion, which is appropriate (the OT sacrificial system was still concerned with being humane to animals), we should affirm that outrage and think of it as common ground to talk about the preciousness of all life God creates. The apostle Paul looked at the altars in Athens and saw something good in them rather than condemning the Athenians for believing in false gods. He found the good impulse that he had in common with them (they worshiped an unseen god) and capitalized on it.
