I have not met any doctor who would perform the  mythical "9 months in the womb but seconds before it would be born" abortion and I doubt you have either.  Also, most doctors only perform abortions after the first trimester in order to save the mother's life.  All the OB/GYNS I know chose that field because they like women and babies, their interest is in preserving life as much as possible. 

I don't like abortion as birth control, most women don't.  However, to assume not using safe birth control is why women have abortions is like saying men use enhancement drugs because they want to make their partner feel better.
