Uwila, I think midwives support natural birth because they see more of it. You just don't get obs/gyn at a homebirth. They tend to see only high risk and emergency cases, and so don't get exposed to normal birth. This is bound to bias your viewpoint ... if 100% of the cases you see are the dramatic ones, that's 100% of your experience and expertise. It must surely pale into the background that you are not seeing, say, 75-80% of births.
Also, obstetricians are fab at surgery and problematic cases. This is where their skill lies, often, and they must have the professional confidence that they can do a good job. Hey, if I was an ace surgeon I would want to intervene and help too - but maybe it would be tempting to intervene a tad too much.
I am a big fan of some midwives, but have encountered others some that in my experience have been terrible ... like every profession, you get your good and your bad. But the midwives I have met who attend homebirths, and are good at sitting on their hands and listening to women are wonderful. They have the experience and knowledge of birth to trust women and how good their bodies are at birthing. They know when to leave well alone, but also when things are not going well.
So its like comparing apples with elephants. They deal on a daily basis with completely different cases. One sees emergencies, and yes will see the disasters, and the other sees the vast majority. Would getting them to argue it out help?
I do agree you can find any study to back up your argument. But that radmid article was a summary of an awful lot of research. I read blinkin loads of research when planning my third child, and saw not a single credible piece of research from any reputable journal that showed that caesareans are safer than vaginal birth in normal circumstances.
Am a big fan of cs for the 5-10% of cases where it saves lives. But not as a vaginal bypass by choice. For me, just personally and with no offence intended, that feels like choosing artificial insemination over sex. Like insemination, cs is great if for valid reasons it cannot happen naturally - and accept that extreme fear, trauma as well as physical reasons can prevent normal birth. But lets face it, its not designed to be a choice substitute for the real thing.
