Honestly OP? Is this a serious question? Normal = it is the norm, i.e. more than 50% of babies are born by vaginal delivery, not by cs.
I totally disagree that describing the way the majority of women give birth as "normal" is in any way a moral judgement on women who give birth by cs. I don't see how this is an issue? The normal way of giving birth is vaginal birth, unless there is a medical reason for another type of delivery, i.e cs. I assume there was a good medical reason for you to have your emcs... how is it a issue by which you are judged/you should judge yourself.
As an aside, this is not to say I am sweeping away any feeling that you may have been traumatised by your DD's birth... that can happen with any type of birth and is, I guess, becasue of the way things were handled and the, frankly, terrifying nature of the whole process. But being traumatised by a scary or degrading experience is not the same as feeling judged... and I think normal is precisely the right term for the method of childbirth that is the norm!
And swapping normal for "unassisted"? Pah! I was GREATLY assisted by my midwife - I couldn't have done it without her!
Tether - in medical terms (and that is what we are talking about), of course abnormal does not have moral connotations. I have abnormally formed eustatian [sp] tubes (tubes in your ear that drain "gunk" away)... that is a fact! Not a moral judgement!
