No argument here. Truth is truth, be it medical or spiritual. Since Christianity is predicated on truth, founded by him to claimed to be Truth embodied [ Jesus said to him, "I am the way, and the truth, and the life; no one comes to the Father but through Me."], we Christians ought to be spreading as much truth as we can.
But we will still try to be faithful to the Great Commission, recognizing that [paraphrasing the Good Book] "what does it profit a woman if she is saved from an abortion, yet loses her soul?"
