This is something that really gets me angry. I have heard stories like this so often where doctors say that they are really pro natural birth, but the moment you are under their care, they do everything in their power to convince you that you're the exception, you're not a good candidate for a natural birth. At least be honest with your patients. Often those same doctors get quite angry when their patients don't trust them. Well, a bit of honesty might help.
It's the same with doctors who apparently support breastfeeding. BUT, only for 6 months, only if you don't smoke, drink, if your baby puts on just the perfect amount of weight (in their opinion), only if you have the perfect diet...

Sorry for the rant...
