As a related aside, I was watching the tv show "Everwood" and the liberal hero was actually refusing to do the requested abortion (leaving it to the conservative doctor who was forced to do it for a variety of reasons not important here), and to justify his refusal, he said "I may not know when life begins, but I sure know when it ends."
Best damn line I ever heard on a television show.
Everwood is one of my daughter's weekly rituals, so I saw that episode too. I was really upset that the Catholic doctor violated his conscience and ended up killing the baby because of some stupid promise he's made to his father, who apparently had been the previous town baby butcher. His mother was the shrill NOW shrew spewing forth the status quo feminonsense. The young woman in question was merely another "I'm just not (insert whine) ready to have a baby!" wealthy, spoiled, and afraid to stand up to her father who didn't want the embarrassment of an OOW grandchild. As I recall, they were careful to keep it from the girl's mother for fear she'd talk the girl out of killing the baby--imagine that!
Gave me some good dialogue fodder with my daughter, though. Since I knew what was going to occur in the storyline, I told her the price of watching it was a conversation on the subject of pregnancy and abortion. Made her stick to the agreement, too.
