I think that part of the problems that we have discussing this is comparing relative levels of pain and discomfort. This is always a tough thing to do at the best of time. Let alone over something as emotionally charged as child birth.
And there is the factor that all births differ, as do all women in the amount of pain produced and crucially percieved.
My best mate had her first birth with no pain relief at all, not because she is a fan of pain, but she never felt overwhelmed by the pain; she was always in control. She was also fortumate enough to have an utterly straightforward delivery, of a good sized baby with a good presentation. She was home withing 12 hours and her next birth was at home
Another mate had a horrific deliverly, masses of pain, felt out of control, had a high forceps delivery at the end, after many attempts at ventouse. Her comment when I asked her how many stitches she had was 'The conly centrefold I'd make nowerdays would be Crossstitch Monthly' . She was in considerable pain after the birth for quite some time.
I had a section. I felt (amazingly) in control, and in very little pain.
If I could chose, I'd have a delivery like my best mate. I'd rather have a good c section than a poor 'natural' delivery.
I could compare my section to either of these vaginal birth stories and come away with different psychological 'outcomes' I think. And for that matter the poor mothers who have posted with crappy C sections would be able to do the same.
And that is where the problem lies, I think. We all view birth in light of our own experiences, and those of our friends an family. So there will be real polarity of feeling on this issue.
A more helpful discussion is how we can move towards all birth experiences being a positive experience wherever humanly possible.
