Because there are certain people and groups who have an agenda to promote X, Y or Z about giving birth.
They hope that whatever Kate does will 'influence other women' and can be used to further their own objects.
If Kate was to go for a natural birth she would be hailed for not being too posh to push and going against 'the celebrity culture of ELCS on maternal request'. (Oh the irony in that route)
Equally if she was to go for a CS, she probably would be hailed in some way by pro-CS activists.
Its highly politicised.
The irony is that what Kate does is none of mine or yours business, and I think the media should respect whatever choice she makes, without prejudice and making it a political issue by shutting the fuck up about it.
Whatever she does will be 'amazing' or a 'failure'. And will be used against the rest of us.
Worst still this idea that women will somehow 'copy' whatever Kate does is deeply patronising and reduces women to idiots incapable of making their own decisions based on their own personal circumstances and instead paints us as sheeple obediently following our leader.
Good luck to Kate, in whatever she chooses and whatever ends up being the end result.
But frankly, I could not give a shit what she does and I think its in the public interest NOT to tell us how she gives birth, because thats the only thing that means that decisions are not being influenced by celebrity power.
