I love the way you put that start, about every person having been carried in some woman's womb.
I think the natural state is to be fascinated by pregnancy - most people would be interested and pleasantly curious if there weren't so much baggage about it. I know men who admit they're a bit jealous we get to know that and they don't - and I think there's no shame in saying that, is there?
With people who are unhappy in their bodies - post-surgery or before - I think what is needed is better support and help, to explain that no, this surgery is not a miracle. It cannot give you a womb. I am not saying that, if you are desperate (and I think some people are immeasurably desperate and unhappy in themselves), you won't want surgery: you probably will. A doctor will possibly let you have it. People may well call you a woman (you will still have to face a lot of people who would have been vile to you before and still will be, or even more so). But you will not have a womb and there's nothing can be done about that.
IMO it's very wrong for women to feel that having a womb isn't an integral part of being a woman - for most people, it is!
That's one point ocured to me ... the other one is, as someone with no kids yet, one of the things I love about MN is people give you a realistic view of pregnancy, no the extremes. It makes me realize how patronizing society in general can be about it. There's two extreme views. Pregnancy is either focused on the a 'miracle' baby (and the mother is better if she suffered hugely ... cf. Daily Mail/Trashy Magazine 'Miracle Baby Jenny survives Mum Sarah's Refusal to treat cancer' stuff). Or pregnancy is a liability, ruins your health, you career prospects, and requires you to be treated like an idiot made of spun glass. I honestly didn't realize before I came on here that some women just get through pregnancy normally without their brains falling out of their ears, the myths are so prevalent. It's good to see more realistic views.
