There is currently a documentary on SBS running, one that explores the minds of the soldiers who perpetrated the Jewish genocide during World War II and those who did the same against the Muslims and Croats in Serbia. The narrator cited that the "us or them" thought was common among all genocides. To such people, the prevailing thought was "to survive, I must kill you."
I realized with a shudder that this is exactly what pro-abortion lobbyists are saying about mothers and the unborn. "In order for me (the woman) to surive, I must kill you (the fetus)." It is a false dilemma, and a deadly one.
