The pro-life strategy should not be to overturn the law, but to change hearts. The best way I've heard it satated is - "It's not so much that we're trying to make abortion illegal, as we're trying to make it unthinkable". If the truth can get out in a loving and compassionate way then the end of abortion is a forgone conclusion. And the truth is that what is being aborted is a living, growing human person occupying the womb. Keep praying.
