"What is a person who abhors abortion, and the circumstances that lead some women to choose it, but believes the decision belongs to the woman and her doctor?"

Pro- abortion.  

It is merely washing ones hands to say pro-choice.  And it is the height of duplicity to claim to abhor abortion and not do everything to get rid of the murderous practice.

The clever semantic games about "fetus" and "zygote" are also merely semantic games.  Have you ever heard a happy woman with a positive pregnancy test joyously exclaim "I'm having a fetus!!!" No, of course not.  This is an unborn child this hand-washing and semantic banter is killing with the scourge of abortion.

By the way...those circumstances you refer to?  Number one reason year after year for abortion?  I don't want a baby now...it would be inconvenient at this time.
