You think rational thought is exasperating? Oh dear. Not only have you committed the fallacy of a false dichotomy - claiming that the NICE is either a 'reliable source' or not - you've also completely failed to see the contradiction in your position. And have demonstrated an astounding ignorance of statistical methods.
It is you who disagrees with the NICE guidelines yet, at the same time, put up a one-pager from the same organisation seemingly in support of your position. That an ELCS is completely unnecessary, etc etc.
However the statistics that you posted claimed no such thing. It is not data 'directly from NICE', i.e. a major study commissioned, performed and controlled by the organisation. It was derived from a series of studies - all of which have different methodologies, sample sizes, etc and condensed into single figures.
The reason NICE gives women a choice is because there is no conclusive evidence either way. No large scale study has been performed taking a majority of the relevant variables into account, if that's even possible. If, this 'reliable source of health data' that you claim to post definitely exists, and it had been conclusively proven. Why would they give people a choice?
Putting statistics all over the place doesn't prove anything. You have to dig deep to understand the variables, confounding factors, etc. Correlation doesn't imply causation.
BTW, I'm not 100% pro-section. I'm still early in my journey and could change my mind still. Despite what you claim I have no 'narrative'. All I have done is explain my reasons for my current leanings, and, multiple times, emphasized that the decision making responsibility lies between women and their medical teams. Who explain the pros and cons of both methods.
I do not claim any expert medical knowledge and so have not deigned to tell people what they should and should not be doing. Unlike you, who keeps making the arrogant presumption of knowing what surgery is 'unnecessary' despite not being medically trained or qualified. It is you who is actively trying to construct a narrative that women are choosing C-sections for frivolous reasons and so shouldn't be given the choice, putting in statistics to support that and getting angry and, erm 'exasperated' when questioned. It is you who claim that women are choosing heightened risks of X and Y with these ELCS while completely failing to acknowledge that risks A and B from a vaginal birth may be less bearable, or the existence of other extenuating factors. All of these will have been explained by the people qualified to do so, to them. They are not making decisions based on the opinion of randoms.
You are not medically qualified nor, from the way you use data even capable of basic statistical reasoning. A little knowledge is a dangerous thing, as you so aptly demonstrate. You're not as clever as you think you are... maybe take some basic courses on critical thinking and the use of statistics in constructing a coherent picture of the true situation.
