"People should have the choice whether to have an epidural or not. "
Well - usually they do have a choice.
And I don't think anyone here is arguing that they shouldn't.
"I can't bear it when people harp on about natural births and no drugs as being the only way forward."
But people don't say that natural birth is the only way to do it.
Do you think - given that nobody here is saying that natural birth is the only way to do it - that perhaps what you actually object to is people airing their very reasonable concerns about the affect of major interventions like epidurals on the normal physiology of labour, and on babies?
Why would it bother you people saying this?
"I don't get why anyone would put themselves through all that pain"
With respect - you obviously haven't read this thread very carefully, because those of us who chose not to have epidurals explained our reasons. I did without it to reduce the risk of injury to me and to my baby and because I value breastfeeding and don't want to put that at increased risk either.
"Natural birth, to me, equates with natural tooth extraction"
It's a bad sad how many people use this analogy - as though normal birth is pathological and as though there is only one person's health at stake instead of two.
