It's this argument we must win.
That’s the way the argument with pro-aborts needs to be framed. Make them defend the concept that one human has the right to take the life of another because that life is not convenient.
Also, remember the most vehement pro-aborts are had-aborts. They KNOW they’ve committed murder, and they have two choices in life - repent before God, or spend their life in rebellion to Him justifying the murder. Most will encourage others to “join” them in their murderous state.
