Ugh.
This type of attitude does/will do a real disservice to your patients. The assumption that anyone who has an abortion does so as a means of birth control is indicative of the fact that your personal opinions and emotional response to even the mention of abortion compromise your ability to objectively evaluate the patient's situation and deliver a best outcome.
There are a million and one reasons why someone may opt for an elective abortion beyond backup backup birth control. The patient may not want to elaborate on those reasons with you, particularly if they feel like their being judged by you--their physician. Whatever the reason the patient has to abort, pregnancy terminations are always a tragic, sad event for everyone involved. It's even more tragic when a patient has to deal with further judgement from her physician for her decision.
If you don't want to perform abortions, don't. You can refrain from being present during them for ethical reasons if you so choose.
It didn't say that anyone who has an abortion does so as a means of birth control. Again, it seems like people hear what they want. A common tactic in the abortion debate.
A million and one reasons, really? Start naming. Here is a link from a study

Rape, incest accounts for less than 1%, but seems to be referred to as the most common reason why abortion should be legal for all.

Maybe I can't add correctly, but according to this study approximately 6% of abortions are related to health care reasons. What about the other 94% of the lives taken because its not convenient or other selfish reasons (notice I didn't use the m word)?
Also, from my own family I know people who were forced to have an abortion. I would never ever judge anyone for this reason. I agree about not knowing the circumstances. Chances are it was for a selfish reason, but I wouldn't judge because it wouldn't be worth hurting the very very few who were forced or truly regret having an abortion.
