Here is an excellent opinion video from "A World Exposure" by Larry Murphy on the opposition Tim Tebow and his mother are apparently facing from Pro-Abortion groups for the Pro-Life ad they have done that is set to air on CBS during the Super Bowl.
Tebow's mother carried him to term and delivered him even though she was facing major medical problems during her pregnancy. She reportedly received advice to end her pregnancy, but made the choice to have Tim.
Tebow wants to share his strong support for Life, and pro-abortion activists are obviously afraid his ad will have a strong impact on the public. They are pressuring CBS to not air the ad.
